Hi!
My recent dwarf2asm.c patch broke powerpc*-*-* bootstrap, while most target
define POINTER_SIZE to (cond ? cst1 : cst2) or constant, rs6000 defines
it to a variable, and the arbitrarily chosen type of that variable determines
whether we get warnings on comparison of that against signed or unsigned
ints.
Fixed by adding a cast.
Tested on x86_64-linux and powerpc64le-linux, committed to trunk as obvious.
