119da46568 sim: unify target->subdir handling for default tests
The testsuite subdir has a note about unifying the target->subdir logic,
so do just that.  The end goal here is to have `make check` work out of
the box without having to delve into dejagnu internals.

The target-specific logic is split out of the top level configure.ac file
and into a dedicated configure.tgt similar to other subprojects (gdb and
ld and etc...) with the difference that this file has to be included at
the m4 level instead of the shell level.  This is necessary only because
autoconf requires AC_CONFIG_SUBDIRS be given a string literal and not a
variable value.

Then the toplevel and the testsuite configure files pull this in, the sim
subdir gets expanded into testsuite/site.exp, and the default sim run code
uses this info to set the sim path to the local compiled run file if it
hasn't already been specified.

c8551de35c sim: fix fpu missing initializer warnings
The current fpu code with externals enabled results in the warnings:
common/sim-fpu.c:2437: warning: missing initializer
common/sim-fpu.c:2437: warning: (near initialization for 'sim_fpu_zero.sign')
common/sim-fpu.c:2440: warning: missing initializer
common/sim-fpu.c:2440: warning: (near initialization for 'sim_fpu_qnan.sign')

So tweak the old style initializers to avoid these.

0d3d2c7158 sim: profile: implement --profile-file backend
The profile code already has options and handling for accepting a file to
write the profile output like the trace code, but it doesn't actually use
it.  At the moment, it simply opens the file at the start and closes it at
the end.  So add two new local functions the way the trace code is doing
it and have them figure out whether to write the output to stdout or the
specified file.  Then convert all existing output in the profile code to
use these helpers.

11409fac6b sim: always enable support for the --endian option
The gdb code always passes down -E <little|big> to the sim core when using
the sim target.  But the sim core only recognizes this option when the sim
supports big endian systems.  So for little endian simulators, any attempt
to use the sim target fails with:

(gdb) target sim
gdbsim: invalid option -- 'E'
unable to create simulator instance

Since always respecting the option doesn't cause any problems, do just
that.  If someone tries to use an invalid endian, they'll get an error
anyways.
