There were a few issues.
- In-tree GCC won't have X_COMPILER_TYPE defined but will have
WANT_COMPILER_TYPE==gcc set from the SYSTEM_COMPILER logic that can
be used. Make the clang check specific to clang as well to ensure
-target doesn't leak into a GCC build.
- When using a cross-compiler GCC (with a default sysroot or arch) and also
passing --sysroot, it basically forgets all internal paths for
libraries. We've already worked around this quite a bit for
the external toolchains. Now for the in-tree bootstrap cross-compiler
GCC, also pass in the needed -B${WORLDTMP}/usr/lib to find the crt
object files, but also -isystem and -L to fix the paths. This creates
quite a spammy build log, but it is clear and still achieves the goals
and stays consistent between internal and external build flags.
Reducing the spam by using the '=' prefix feature will help and be
done later.
