The amd64 multilib of boehm-gc doesn't build on i386-pc-solaris2.10: the
compilation fails with
/vol/gnu/src/gcc/gcc-dist/boehm-gc/include/private/gcconfig.h:435: error: parse
error before '--' token
Environment:
System: SunOS cumaru 5.10 Generic_Patch i86pc i386 i86pc

Fix:
I've added a clause to boehm-gc/include/private/gcconfig.h for
X86_64/SUNOS5 to allow boehm-gc to compile, but gctest doesn't fully work
yet (but at least as well as the 32-bit version). Cf. PR libgcj/21940 for
32-bit gctest failures on this platform.
