test failures with gcc 4.4

[Chris Metcalf]

I went ahead and created a new "Compiler-dependent" section on the 2.20 release wiki page for build and test failures, and a "gcc 4.4" section under that, and mentioned the ISO11 conform tests, the __SIG_ATOMIC_TYPE__ issue, and the build failures on the elf/tst-unique[34] tests.

Unfortunately the elf/tst-unique{3lib,4lib,3lib2}.so are build failures and so cause "make -k check" to fail to complete and as a result I just end up commenting them out in elf/Makefile, which isn't particularly clean.
