We don't have yet any checks in the testsuite whether the compiler
supports __thread.  But, perhaps just compiling/ld -r'ing/linking
__asm (".tls_common foo,4,4");
int main (void) { return 0; }
would be enough.  But then again, we need some test to see whether
the target supports TLS at all.  The current TLS tests are all in
ld-<cpu>/ ATM, but this test isn't arch specific.
