please add to stable kernel v3.9
this patch is a merge of upstream commits 
	93782eba49e23c3f311a6b05a19ba15927ec4e8b
and
	6880b0150a7c25fd75c5ece80abc49ebf53c38c1


People/distros vary how they prefix the toolchain name for 64bit builds.
Rather than enforce one convention over another, add a for loop which
does a search for all the general prefixes.

For 64bit builds, we now search for (in order):
	hppa64-unknown-linux-gnu
	hppa64-linux-gnu
	hppa64-linux

For 32bit builds, we look for:
	hppa-unknown-linux-gnu
	hppa-linux-gnu
	hppa-linux
	hppa2.0-unknown-linux-gnu
	hppa2.0-linux-gnu
	hppa2.0-linux
	hppa1.1-unknown-linux-gnu
	hppa1.1-linux-gnu
	hppa1.1-linux

This patch was initiated by Mike Frysinger, with feedback from Jeroen
Roovers, John David Anglin and Helge Deller.

I prefer to take the original upstream patches, so I've just applied
both of these, instead of your merge.

thanks,

That's absolutely fine.
