While `pc` is not particularly wrong on x86_64, it's nonsensical on other supported platforms, namely aarch64 and riscv64. For consistency, we now don't use this vendor anymore, regardless of the platform. Within the LLVM project, we now build as `$arch-serenity`. This is enough in most cases, the only place where we have to specify a vendor is the target .cfg file where we use `$arch-unknown-serenity`. When building GCC and friends, again we simply identify as `$arch-serenity` and this is enough. As a result, the tools in Toolchain/Local/$arch/bin are now named after this pattern: `$arch-serenity-$tool`. These changes affect the toolchain build scripts, serenity's build scripts and the Ports. The last place where we should see `x86_64-pc-serenity` is the output of `config.sub`, which assume the vendor is `pc` on vendor-less `x86*` triples. So `x86_64-serenity` is expanded to `x86_64-pc-serenity`, luckily enough and AFAICT, the whole GNU ecosystem considers `pc`, `unknown` and vendor-less target triples the same. So `configure` shouldn't have an issue finding the right tools anyway. The gn files were edited with sed and are not tested. This commit also includes a check in `Meta/serenity.sh` to give a nicer error message when trying to build the system with an old toolchain. ---- To test this patch, on a clean tree I: - Ran `./Meta/serenity.sh x86_64 GNU` - Ran `./Toolchain/BuildJakt.sh` - Tested these ports: python3(configure based), libjxl(cmake based) and rizin(meson based) - Also booted on aarch64 and risv64 I also repeated the steps above with a Clang toolchain. On a working tree I tested all the affected ports, the results are: - tinycc build fine but can't compile programs, I observed the same on master. - gdb and epsilon don't build but report the same errors as on master. - I manually edited the libgpg-error, and it builds fine. - The gcc port works fine.

# FIXME: We could eliminate this setting by building LibC and support asm files (crti.o, crtn.o)
|
|
# in a separate build stage before the main build to ensure that LibC is available
|
|
# for the try_compile check for the main build.
|
|
# Note that `set(CMAKE_TRY_COMPILE_TARGET_TYPE STATIC_LIBRARY)` is not a suitable replacement,
|
|
# since applications might try and use `try_compile()` to detect which library a symbol is in,
|
|
# which doesn't work when using static linking.
|
|
# Instead, just tell CMake directly that the compiler works fine, so that it doesn't have to run
|
|
# a compile check before the build.
|
|
# This also means that the "Detecting C{,XX} compiler ABI info" step fails, so we need to set

# some variables manually. There may be more variables that aren't set, but those don't seem to be
|

# necessary at the time of writing this. We only support 64-bit little endian systems, so set the
