kbuild: move -fno-dwarf2-cfi-asm to powerpc only
Better dwarf2 unwind information is a good thing, it allows better
debugging with kgdb and crash and helps systemtap.
Commit 003086497f07f7f1e67c0c295e261740f822b377 ("Build with
-fno-dwarf2-cfi-asm") disabled some CFI information globally to work
around a module loader bug on powerpc.
But this disables the better unwind tables for all architectures, not just
powerpc. Move the workaround to powerpc and also add a suitable comment
that's it really a workaround.
This improves dwarf2 unwind tables on x86 at least.
