compilers: Check if GCC has support for ObjC and/or ObjC++

Since this is optional, we should not accept that GCC is a valid ObjC or
G++ is a valid ObjC++ Compiler unless we've tested that they can
actually do a basic compile.

This requires fixing a number of tests that have broken assumptions. In
some cases I've split tests where issues with one language would hide
the other. It would be great if we had a competent test framework that
allowed subtests to skip, unfortunately we have python's unittest
instead. Because of that we can't avoid extra tests by use of subtests.
