Patch from Stefan Allius for libgcc multilib support
this is the last patch, we need to make the support of multitarget libgcc complete. --------------------------------- In ldso/ldso/Makefile I added the CPU_LDFLAGS-y to the LDFLAGS --------------------------------- In libc/Makefile I set the LDFLAGS for the script get-needed-objects.sh with CPU_LDFLAGS-y --------------------------------- In extra/scripts/get-needed-object.sh we now use the LIBGCC from Rules.mak and call LD with LDFLAGS (==CPU_LDFLAGS-y). Addtionally I grep the NM output, to fix the unresolved external __GLOBAL_OFFSET_TABLE__ on SuperH targets. ---------------------------------
