JS, at least, doesn't need bindgen at this point. If JS does start
requiring bindgen under certain build configurations, we'll have to
figure out what to do about the bindgen dependency at that point:
require bindgen always, or just require bindgen for the
configuration(s).
Currently, --enable-lto just implies --enable-linker=lld, which
essentially only works on Linux, and assumes one can't do lto with
anything other than lld. Which is not true. As a matter of fact, even
ld.bfd can do lto, as long as the gold plugin for llvm is available,
or when doing lto with GCC instead of clang.
Anyways, to allow more lto setups, we adapt the --enable-linker setup
to:
- work on macOS, which it currently doesn't, and add support for the mac
linker (ld64), which, unfortunately, doesn't have a clean way to be
detected, so work around that.
- default to lld if lto is enable, no linker was explicitly given, the
compiler is clang *and* the build target is not macOS.

Because we have no linking configure test in python configure (yet), we
just make old-configure tests use LINKER_LDFLAGS, and make those flags
added to LDFLAGS by old-configure at the same time.

The intent is for the build system to soon require Node.js to build
Firefox. But we aren't ready to make Node.js a build requirement
just yet.
The goal of this commit is to implement configure detection for
Node.js so that we can a) work out detection bugs b) give people a
means to validate system compatibility *before* we throw the switch to
require Node.js.
This commit introduces configure logic for finding a Node.js
executable, resolving its version, and validating its suitability.
By default, if Node.js cannot be found or there is an error resolving
its version, we print some warning messages and move on.
If --enable-nodejs is used (not the default), errors are raised
if Node.js cannot be found or its version isn't suitable.
Once we require Node.js, the added code can likely be simplified.
When writing the code, I went out of my way to make failures as
non-fatal as possible. e.g. normally we'd say that failures to run
`node --version` would be fatal. I'm purposefully trying to not have
this configure check break anyone's environment, even if failure
occurs. Again, the goal is to introduce the configure checks first
in a non-fatal way such that we can debug failures so the flag day
transition is simpler.

We're well overdue for an upgrade of the rust compiler requirements.
Now that we're building with 1.28 (albeit a beta, due to be bumped when
it's released), we can bump the requirement away from 1.24 which is now
old. 1.27 is too new, though, so settle for the older 1.26.

When I originally implemented bug 1458161, this is how it was done, but
it was suggested to use a configure-time check. This turned out to not
be great, because the rust compiler changes regularly, and we don't run
the configure tests when the version changes. When people upgraded their
rust compiler to 1.27, the code subsequently failed to build because the
features were still set for the previous version they had installed.

When we're running using pipenv, we have more than one virtual environment. This means the current check to see if python matches the initial virtual environment gives a false positive when we're in a secondary virtual environment. This patch changes the condition to check if the current python path exists within the virtual environments root directory.

We used to do that before bug 1455767. Taking a step back, what we want
(and what this change implements) is to:
- allow to specify a linker to use explicitly
- check that using the corresponding linker flags makes us use that
linker
- if no linker is specified, and developer options are enabled, we want
to try to use gold if it's available, otherwise, we want to detect
what kind of linker the default linker is
- if --disable-gold is explicitly given, we don't want to automatically
use it.

--enable-release not being passed means developer options are enabled,
which is generally speaking not desirable for builds meant to be
shipped. This is somewhat alleviated for Firefox by MOZILLA_OFFICIAL
implying --enable-release (as well as MOZ_AUTOMATION), but that doesn't
apply to e.g. standalone js builds (even some of the standalone js jobs
on our automation don't set MOZ_AUTOMATION for some reason).
A reasonable thing to do is just to default builds for release/beta
milestones to --enable-release, but still allow --disable-release
to enable the developer options.

This option does nothing if it's provided, and things will probably
break in some most peculiar manner if somebody uses --without-pthreads.
Given that neither outcome is useful, we should remove the option.
