[Buildroot] [PATCH 1/1] toolchain/toolchain-buildroot: PPC64 support in musl requires ALTIVEC

musl assumes all PPC64(LE) CPUs support ALTIVEC instructions. However,
the e5500 does not support ALTIVEC so builds targeting this CPU using
musl will generate illegal instructions.
Disable musl if the PPC64(LE) CPU does not support ALTIVEC instructions.
