As Dominique pointed out last night, g++.dg/abi/key2.C needs adjustment.

This is supposed to test that we emit the right sections for things that need
coalescing - which now only applies to older linkers.  So the fix here is to
make it test for correct output with a forced old linker.

We could add a new test to see that the non _coal,coalesced sections are
emitted for new linkers, but that's probably a moot point since many other
tests would fails (as per this PR).
