The message "mathvec needs GCC version 4.5 or later" is not appropriate in
current glibc; glibc already requires GCC 6.2 or later to build.
Is this configure test for compiler support actually needed, or does it
suffice to build all the relevant files with -mvsx? That is, are there
any 64-bit configurations where -mvsx would produce a compilation error?
