For this case, or such cases that use pkg-config to compute paths for 
LIBS (such as zlib), they have different behaviors:

* multilib enabled build:

$ bitbake gnutls -cdevshell
$ pkg-config --libs zlib

-L/buildarea/raid5/wfan/yocto/builds/poky-build/tmp/sysroots/qemux86-64/usr/lib64 
-lz

* build w/o multilib

$ bitbake gnutls -cdevshell
$ pkg-config --libs zlib

-lz

This is where the buildpaths from for target pkgconfig files. Ideally it 
should be fixed from pkg-config side, but just fix it with sed is 
acceptable I think if the former is impossible.

I'll investigate more about that. Do you know where the difference from?

Thanks
