[Qemu-devel] [patch] Use fabs

[Paul Brook <paul@codesourcery.com>]

target-ppc/op_helper.c uses fabsl (which operates on a "long double" value) to 
get the absolute value of a "double" value. The patch below changes this to 
fabs. fabsl is significantly slower on some hosts, and not present on others.
