[Bug target/24465] New: -mminimal-toc miscompilation of __thread vars

[amodra at bigpond dot net dot au]

RS6000_PIC_OFFSET_TABLE_REGNUM isn't being set up for functions that don't need
a constant pool but access __thread vars using __tls_get_addr.

/* Fails with -m64 -mminimal-toc -fPIC */
static __thread int x;
int foo (void)
{
  return x;
}

This is the reason why powerpc64 has been getting lots of libjava failures
since this libjava change: 2005-09-27  Tom Tromey  <[EMAIL PROTECTED]>
