[OE-core] [PATCH 0/4] base/bbclass: use target path to replace build ones in debugging info

[Richard Purdie]

I like the idea of this a lot, I think it makes sense however why not
just:

diff --git a/meta/conf/bitbake.conf b/meta/conf/bitbake.conf
index e80ee18..284f7fb 100644

 DEBUG_OPTIMIZATION = "-O -fno-omit-frame-pointer ${DEBUG_FLAGS} -pipe"

?

Cheers,
