LOG: [libc][mathvec] Fix missing ABI-prefix from causing errors (#210127)

abi_prefix.h throws errors for unsupported ABI targets. This patch
modifies that behaviour to instead fall back onto a default
naming scheme instead, as to not break non-vfabi supporting targets.

Added: 
    

Modified: 
    libc/src/mathvec/abi_prefix.h

Removed:
