>Description:
When using any native pkgconfig enabled component (with shared-mime-info), 
work/.tools/bin/pkg-config does not find modules, whereas 
/usr/pkg/bin/pkg-config run directly does. Problem is that the wrapper script 
forces libpath to work/.buildlink/lib/pkgconfig, which is populated only with a 
_subset_ of /usr/pkg/lib/pkgconfig, not from $PKG_CONFIG_PATH.

Note that I have already copied every native .pc file (e.g. 
/usr/lib/pkgconfig/libxml-2.0.pc) from $PKG_CONFIG_PATH to 
$PREFIX/lib/pkgconfig, so even the full pkgsrc pkgconfig set isn't symlinked.
>How-To-Repeat:
pkgsrc-current: cd pkgsrc/databases/shared-mime-info; bmake

rousku:~/Projects/pkgsrc/databases/shared-mime-info admin$ 
work/.tools/bin/pkg-config --libs "\
                  libxml-2.0 >= 2.4 \
                  glib-2.0 >= 2.0.0"
Package libxml-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libxml-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libxml-2.0' found
rousku:~/Projects/pkgsrc/databases/shared-mime-info admin$ 
/usr/pkg/bin/pkg-config --libs "\
                  libxml-2.0 >= 2.4 \
                  glib-2.0 >= 2.0.0"

>Fix:
1) Don't override the libpath in the wrapper script, or 2) populate 
work/.buildlink/lib/pkgconfig from $PKG_CONFIG_PATH (or even the full 
$PREFIX/lib/pkgconfig). Or as a workaround: "bmake wrapper; cd 
work/.buildlink/lib/pkgconfig; ln -s /usr/pkg/lib/pkgconfig/* ."
