powerpc: Limit ARCH_HAS_KERNEL_FPU_SUPPORT to PPC64
When building a 32-bit kernel, some toolchains do not allow mixing soft
float and hard float object files:
LD vmlinux.o
powerpc64le-unknown-linux-musl-ld: lib/test_fpu_impl.o uses hard float, arch/powerpc/kernel/udbg.o uses soft float
powerpc64le-unknown-linux-musl-ld: failed to merge target specific data of file lib/test_fpu_impl.o
make[2]: *** [scripts/Makefile.vmlinux_o:62: vmlinux.o] Error 1
make[1]: *** [Makefile:1152: vmlinux_o] Error 2
make: *** [Makefile:240: __sub-make] Error 2
This is not an issue when building a 64-bit kernel. To unbreak the
build, limit ARCH_HAS_KERNEL_FPU_SUPPORT to 64-bit kernels. This is okay
because the only real user of this option, amdgpu, was previously
limited to PPC64 anyway; see commit a28e4b672f04 ("drm/amd/display: use
ARCH_HAS_KERNEL_FPU_SUPPORT").
Fixes: 01db473e1aa3 ("powerpc: implement ARCH_HAS_KERNEL_FPU_SUPPORT")
