    util/crossgcc/buildgcc: correct clang test
    
    On certain versions of /bin/sh the following sequence
    causes problems.
    '$CC --version | grep clang &>/dev/null && ...'
    
    I'm not sure how bash handles that case, but it's effectively
    forking grep off into the background and always evaluating an
    empty statement to /dev/null while unconditionally running
    whatever follows &&.
