testsuite: i386: require glibc for C99 libm in vectorize-aocl1.c

x86_64-elf fails gcc.target/i386/vectorize-aocl1.c because various
functions aren't recognized as builtins because the target isn't
assumed to offer C99 math library functions, and then the expected
transformations don't occur when calling them.

It would presumably be possible to adjust the test so that it passes
under such conditions, but I'm not undertaking that.  Requiring glibc
isn't quite ideal, but it's probably good enough, even though the test
makes some effort to compile with other libraries.
