If I understand this correctly, it is checking that the
target HW actually supports the Neon extension.
Is this right?

Where does this get invoked?

I think I am on the edge of understanding a solution

for MMX, SSE,  Altivec, and any other odd multilib
CPU option that the test suite hits and a particular
target CPU does not support.  Right?
