[PATCH] parisc: autoselect 32/64bit compiler

[Helge Deller]

Automatically select correct 32- or 64bit (cross) compiler, independent if
the kernel is built locally (e.g. 64bit kernel target on 32bit userspace) or 
cross-compiled from another architecture. This patch allows one to just
run 
	make ARCH=parisc	when run as cross compiler, or just
	make 			when run locally.

Just ignore/drop this patch.
Although IMHO the idea is good, it breaks if people name their
(cross-)compiler "hppa-linux-gcc" instead of "hppa-linux-gnu-gcc".
