test failures with gcc 4.4

[Chris Metcalf]

I notice that there are some issues with older gcc for the tests. We've already had a discussion about the failures building elf/tst-unique{3lib,4lib,3lib2}.so here:

https://sourceware.org/ml/libc-alpha/2012-06/msg00430.html

but I don't see those failures mentioned yet anywhere in the test results page.

Similarly, my conform results show a bunch of failures from using gcc 4.4, which I summarize under the TILE-Gx section (for now) as:

- The ISO11 conform tests fail because gcc 4.4 does not support "-std=c1x"
- The inttypes.h and stdint.h conform tests fail because gcc 4.4 does not define __SIG_ATOMIC_TYPE__

Would it make sense to create a new section on the 2.20 release wiki page for compiler-specific failures and put all of these in that section?  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.
