When I try to cross compile a ppc64 kernel, it generally fails on the VDSO stage. This is true for powerpc64 cross- compiler, but also when I try to build a ppc64le kernel on a ppc64 host.
VDSO64L fails: VDSO64L arch/powerpc/kernel/vdso64/vdso64.so.dbg /usr/bin/powerpc64-linux-gnu-ld: arch/powerpc/kernel/vdso64/sigtramp.o: file class ELFCLASS64 incompatible with ELFCLASS32 /usr/bin/powerpc64-linux-gnu-ld: final link failed: File in wrong format This fails because gcc calls "collect2" with "--oformat elf32-powerpcle" with ppc64 objects, without the "--oformat" ld works well because it use the format of the first object as output format. As this case is correctly managed to build the other kernel objects, this patch replaces $(GCC) by $(LD) to generate the VDSO objects.
