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.
