Hi!
As having to depend on gcc 4.6+ on i386 is kindof a waste on 9.1+
where we have clang too, and clang might generate better code than
the old gcc 4.2.1 in base on amd64 anyway I thought what if we have
the vlc port default to using clang on 9.1+ when it's available?
So I propse the patch below for testing by anyone on 9.1 or later,
also on i386 where I can't test myself, please report any issues
or regressions you find.
Thanx!
Juergen
