- Replaced "which" with a /bin/sh script snippet. - inspired by Sven-Ola Tuecke: avoid a bash'ism (i.e. "OPTS="${OPTS//$opt}") in   gcc-warnings and ld-warnings. But we do not replace it with `sed` (since it   costs a fork(2) and an exec(3)) but also with shell code which doesn't use   any external program.
