configure.ac: unbreak the build with non gnu grep
181581280b
changed the way the
llvm-config version is read from sed to grep and introduced
a requirement for gnu grep extension that treats BREs as EREs.
Avoid this by calling egrep instead of grep which should be
able to handle EREs everywhere.
This allows Mesa to build on OpenBSD again.
