Bug#644986: i386: Compiling gcc-snapshots from upstream with multiarch-toolchain?

[Sedat Dilek <sedat.dilek@googlemail.com>]

[ RESEND ]

I played again with CFLAGS_FOR_TARGET and CXXFLAGS_FOR_TARGET by exporting them.

-I/usr/include/${HOST_SYSTEM_MULTIARCH_TYPE} ...
...catches the gnu/stub-32.h issue.

-B/usr/lib/${HOST_SYSTEM_MULTIARCH_TYPE} ...
...does NOT catch the problem with crt*.o files.

-B/lib/${HOST_SYSTEM_MULTIARCH_TYPE}
-B/usr/lib/${HOST_SYSTEM_MULTIARCH_TYPE} ...
... NOPE, too.
