[ppc64-linux]: Compute u-area offsets of FP registers correctly

[Jim Blandy]

2003-06-06  Jim Blandy  <jimb@redhat.com>

	* ppc-linux-nat.c (ppc_register_u_addr): Correctly compute u-area
	offsets for floating-point registers in both 32- and 64-bit
	interfaces.

If I'm not mistaken, this patch has been rolled into

    http://sources.redhat.com/ml/gdb-patches/2003-06/msg00326.html

which has already been approved.

(If I am mistaken, let me know, and I'll take another look.)
