My machine is Fedora 20 x86, and staticthreads.c can't be compiled
like this:

Executing on host: gcc
../../../../git/gdb/testsuite/gdb.threads/staticthreads.c  -static
-DHAVE_TLS -g  -lpthread -lm   -o

   (timeout = 300)
spawn -ignore SIGHUP gcc
../../../../git/gdb/testsuite/gdb.threads/staticthreads.c -static
-DHAVE_TLS -g -lpthread -lm -o

My glibc version is 2.18 12.fc20 and gcc version is 4.8.2 7.fc20.
