Authentication-results: sourceware.org; auth=none

Hi,
This patch is the second part fixing memset-inline-{4,5,6,8,9}.c failures on
cortex-a9.  It adds a function checking CPU tuning information in dejagnu,
it also uses that function to skip related testcase when we are compiling
for cortex-a9 tune.

Build and test on arm-none-eabi.  Is it OK?
