I tested on a Ubuntu 14.04 (kernel 3.13.0-35-generic, GCC 4.8.2, binutils 2.24)
and I only see:
The 'nptl/tst-stack4' seems to be a timing issue, since it is sporadic and running
manually it does not show the issue:
$ ./testrun.sh nptl/tst-stack4; echo $?
Your 'math/test-double' and 'math/test-float' are a libgcc issue which are fixed in
GCC 4.9 .
The 'math/test-ldouble' issues are know from previous GLIBC version and it mainly
related to libgcc issues as well  . 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.
