File tls-no-direct.diff of Package libgcj48

For i?86 negative offsets to %fs segment accesses cause a hypervisor
trap for Xen.  Avoid this by making accesses indirect.

???  Note that similar to the behavior on SLE11 this only affects
the compiler built on %ix86, not that on x86_64, even with -m32.
