[oe] New kmod {libdir} breaks udev 182 build

[Thilo Fromm]

Hi guys,

I've got an issue with
openembedded-core/meta/recipes-kernel/kmod/kmod_git.bb, with the way
{libdir} is set in line 19:

libdir = "${base_libdir}"

"git blame" claims this was added by Khem Raj on 2012-05-08. This line
causes libkmod to put its pkgconfig ".pc" file in the staging area at
"/lib/pkgconfig/libkmod.pc". This is sad because other recipes would
only look at /usr/lib/pkgconfig/ and /usr/share/pkgconfig.

Take meta-openembedded/meta-oe/recipes-core/udev/udev_182.bb, for
example. The build predictably fails with

checking for KMOD... no
configure: error: Package requirements (libkmod >= 5) were not met:

No package 'libkmod' found


So what's the right thing do do here? Use a different package install
path for libkmod, or point udev to /lib/pkgconfig by extending its
PKG_CONFIG_PATH correspondingly?

Regards,
Thilo
