James Clark c3a8f85351 perf test: Add mechanism for skipping attr tests on auxiliary vector values 
This can be used to skip tests or provide different test values on
different platforms. For example to run a test only where Arm SVE is
present add this to the config section:

  auxv    = auxv["AT_HWCAP"] & 0x200000 == 0x200000

The value is a freeform Python expression that is evaled in the context
of a map called "auxv" that contains the decoded auxiliary vector.
