Everything seems to work find until I enable "valgrind".  'bitbake' fails to compile valgrind

Seems like many people were running into this issue for many reason.  Saw a lot of suggestion in google, but seem like there is no real solution...
I try to create valgrind_%.bbappen with the following contents.  And did not help...

Any suggestion is appreciated.

It looks like you are just missing a soft-float library but I don't know
off-hand where that is.

We have a recent commit:

https://git.openembedded.org/openembedded-core/commit/?id=effd1434a6ca6afcc358bea64053a7bf805633c7

valgrind: disable it for powerpc soft-float
valgrind doesn't build for powerpc soft-float. It is thus disabled for
such architectures.

so it seems that powerpc-nf is just not supported by valgrind yet.


An examples that shows what sort of changes would be needed:

https://sourceware.org/git/?p=valgrind.git&a=search&h=HEAD&st=commit&s=soft-float

Good luck,
