I have checked the gcc sources and this is used only for rs6000.
I think you should tell upstream about it, because this is glibc
As of gcc-cvs the linux-unwind.h file should have
#ifndef inhibit_libc at the beginning and #endif at the end
(this would ensure, that cross-compiling will work)
currently (gcc-cvs) has this only for i386 and mips, but should have it
probably for all archs
