https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227920 --- Comment #12 from Mark Millard <marklmi26-fbsd@yahoo.com> --- (In reply to Kenneth Salerno from comment #5) Summary of a failure: When a clang-based environment tries to build a target by building gcc 4.2.1 as the boottrap compiler, it looks like LIB32CFLAGS ends up being used on the bootstrap compiler's cpp line: it ends up being rejected by the gcc 4.2.1 related cpp. More detailed evidence: I tried to cross build amd64 -> powerpc64 where the cross build built gcc 4.2.1 to do the later build stages. I used the Makefile.libcompat patch variant below: # svnlite diff /usr/src/Makefile.libcompat Index: /usr/src/Makefile.libcompat =================================================================== ---
