Daniel Kolesa 1b9fce56c4 util: add auxv based PowerPC AltiVec/VSX detection
At least on Linux, we can use the ELF auxiliary vector to
detect the presence of AltiVec, VSX and other CPU features
without having to go through handling SIGILL, which has
various problems of its own.

A similar thing is already being done for ARM to detect NEON.
