[Buildroot] [PATCH v2 1/1] toolchain/toolchain-buildroot: PPC64(LE) support in musl requires ALTIVEC

[Vincent Fazio]

musl currently assumes all PPC64(LE) CPUs support ALTIVEC instructions.

However, there are exceptions (such as the e5500) for which musl builds
ultimately generate illegal instructions for the targets.

Disable musl if the PPC64(LE) CPU does not support ALTIVEC instructions.

This patch addresses the issues seen here:
