util/crossgcc/buildgcc: correct clang test
On certain versions of /bin/sh the following sequence
causes problems.
'$CC --version | grep clang &>/dev/null && ...'
The above is a bashish for 2>&1 >/dev/null. However, buildgcc
is interpeted by /bin/sh which doesn't necessarily mean bash.
On dash it's effectively forking grep off into the background
and always evaluating an empty statement to /dev/null while
unconditionally running whatever follows the &&.
