Author: bdrewery Date: Tue Aug 23 19:29:37 2016 New Revision: 304695 URL: https://svnweb.freebsd.org/changeset/base/304695 Log: Fix in-tree GCC builds after r304681. 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.
