Since 32ef9e5054ec, -Wa,-gdwarf-2 is no longer used in KBUILD_AFLAGS.
Instead, it includes -g, the appropriate -gdwarf-* flag, and also the
-Wa versions of both of those if building with Clang and GNU as. As a
result, debug info was being generated for the purgatory objects, even
though the intention was that it not be.
Fixes: 32ef9e5054ec ("Makefile.debug: re-enable debug info for .S files")

Difference from v2: replace each AFLAGS_REMOVE_* assignment with a
single aflags-remove-y line, and use foreach to add the -Wa versions,
as suggested by Masahiro Yamada.
