Judging from `run.do_compile.6321` `PKG_CONFIG_PATH` gets set
incorrectly.

        export PKG_CONFIG_PATH="/oe/build/angstrom-dev/sysroots/armv7a-angstrom-linux-gnueabi/usr/lib/pkgconfig:/oe/build/angstrom-dev/sysroots/armv7a-angstrom-linux-gnueabi/usr/share/pkgconfig"

I checked `gnome-doc-utils.pc` in these directories and both point to
`/usr/share/xml/gnome/xslt/docbook/omf/db2omf.xsl`, which is incorrect
(`datadir=/usr/share`)

In the staging(?) path
`/oe/build/angstrom-dev/sysroots/i686-linux/usr/lib/pkgconfig/`
everything is set up correctly.

        datadir=/oe/build/angstrom-dev/sysroots/i686-linux/usr/share

Also running 

        /oe/build/angstrom-dev/sysroots/i686-linux/usr/bin/pkg-config --variable db2omf gnome-doc-utils

in a clean environment without exporting `PKG_CONFIG_PATH` works.

Is this a problem with new style staging? Could you please provide a
hint on how to fix this.


Thanks,

Paul
