The WITHOUT_LIB32= based build completed.

So it looks to me like the -B handling logic in the build
environment for FreeBSD may need some work for lib32 capable
contexts for cross-toolchain builds.


I'll note that gcc/g++ reports for its -B option:

QUOTE
`-B' prefixes that effectively specify directory names also apply to libraries
in the linker, because the compiler translates these options into `-L' options
for the linker. They also apply to includes files in the preprocessor, because
the compiler translates these options into `-isystem' options for the
preprocessor. In this case, the compiler appends `include' to the prefix.
END QUOTE

This would make using a non-directory different than pointing -B to a
directory,
at least for gcc/g++ cross tools.


But I did not find any wording about the handling of multiple -B's on
the command line.
