[Buildroot] Status of valgrind on powerpc

[Thomas De Schampheleire]

[now sending correctly to the mailing list as well]

Hi,

I'm wondering what the status is of building valgrind for powerpc...

Not so long ago, the powerpc package was not available for powerpc;
Peter disabled it because a.out is missing.
But recently, Thomas enabled powerpc building again, with commit
http://git.buildroot.net/buildroot/commit/?id=afabcb63816806aa8c971000c486f4e108aeb117
(valgrind: bump to 3.6.1 and add support for ARMv7)
Also recently, I see a patch from Baruch Siach (valgrind: workaround
for segmentation fault on PowerPC) that hints that valgrind should at
least build for powerpc.

If I try this, I get:

Hence my question: is it supposed to work now? If yes, what am I
missing? (This is buildroot-2011.05 with the latest valgrind changes).
I will try buildroot-2011.08 to see if it works better.

Thanks,
Thomas
