I updated the tilepro/tilegx section for the Release/2.16 wiki
appropriately.  I asked our gcc point person to let me know how to
reference the remaining open issue with -fexception support and I'll update
the wiki when I hear back from him.

I have some unresolved questions from an email I posted earlier
(http://sourceware.org/ml/libc-alpha/2012-05/msg01204.html).  In a very
vanilla build of the current glibc tip on x86_64 RHEL 6.2, using just
"configure --prefix=/usr --enable-add-ons=nptl", I get failures in
elf/tst-unique{3lib,4lib,3lib2}.so of the form:

elf/tst-unique3lib.os:(.data.DW.ref.__gxx_personality_v0[DW.ref.__gxx_personality_v0]+0x0):
 undefined reference to `__gxx_personality_v0'

Perhaps I'm missing something, but AJ reports no testsuite failures with
newer components.  RHEL 6.2 is kernel 2.6.32, gcc 4.4.6, binutils
2.20.51.0.2, and one of those might be responsible for the difference.  If
this is a well-known issue it would be nice to track it.

My immediate selfish motivation is that I feel like I need to report this
as a testsuite failure, but if it's really a generic issue (and it does
look like it), I'd rather report it that way and not incriminate
tilepro/tilegx any further :-)
