powerpc/vdso: Include CLANG_FLAGS explicitly in ldflags-y
[ Upstream commit a7e5eb53bf9b800d086e2ebcfebd9a3bb16bd1b0 ]
A future change will move CLANG_FLAGS from KBUILD_{A,C}FLAGS to
KBUILD_CPPFLAGS so that '--target' is available while preprocessing.
When that occurs, the following error appears when building the compat
PowerPC vDSO:
clang: error: unsupported option '-mbig-endian' for target 'x86_64-pc-linux-gnu'
make[3]: *** [.../arch/powerpc/kernel/vdso/Makefile:76: arch/powerpc/kernel/vdso/vdso32.so.dbg] Error 1
Explicitly add CLANG_FLAGS to ldflags-y, so that '--target' will always
be present.
