Devel::CheckLib's _findcc() function first looks to see if the Config
variable is -x-able. If it's not, it looks everywhere in the $ENV{PATH}
for it, which is what 'which' is supposed to do.
There's also some trickery in there for dealing with cases where
$Config{cc} is "foo cc" where foo can be a shell script or similar
for doing things like parallelising builds.
