I tested on a Ubuntu 14.04 (kernel 3.13.0-35-generic, GCC 4.8.2, binutils 2.24)
and I only see:

FAIL: math/test-ildoubl
FAIL: math/test-ldouble
FAIL: nptl/tst-stack4

The 'nptl/tst-stack4' seems to be a timing issue, since it is sporadic and running
manually it does not show the issue:

$ ./ nptl/tst-stack4; echo $?

Your 'math/test-double' and 'math/test-float' are a libgcc issue which are fixed in
GCC 4.9 [1].

The 'math/test-ldouble' issues are know from previous GLIBC version and it mainly
related to libgcc issues as well [2] [3].  Joseph has advocate to fix some of them,
but there not yet correct in GCC.  I also believe they might have some lingering 
exception handling needed in GLIBC, but I didn't take a deep look yet.

I do not see 'posix/tst-chmod' and 'posix/tst-getaddrinfo5'.  The 'tst-chmod' does
look a kernel issue, which 'tst-getaddrinfo5' seems something related to you system
IMOH.  The 'rt/tst-cpuclock2' I only see on a powerpc64 box (Fedora 19), which I 
also think it is a kernel issue.
