    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.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.target/i386/vectorize-aocl1.c: Require glibc.
