`make checkstack' and cross-compilation

[Geert Uytterhoeven]

Makefile has:
| # Use $(SUBARCH) here instead of $(ARCH) so that this works for UML.
| # In the UML case, $(SUBARCH) is the name of the underlying
| # architecture, while for all other arches, it is the same as $(ARCH).
| checkstack:
|         $(OBJDUMP) -d vmlinux $$(find . -name '*.ko') | \
|         $(PERL) $(src)/scripts/checkstack.pl $(SUBARCH)

While this may fix `make checkstack' for UML, it breaks cross-compilation.
E.g. when cross-compiling for PPC on ia32, ARCH=powerpc, but SUBARCH=i386.

Probably it should use SUBARCH if ARCH=um, and ARCH otherwise?
