Worse, it might use the host systems pkgconfig which might have broken
sysroot support or suffer from some other issues our own pkgconfig does
not.

E.g:

http://git.pokylinux.org/cgit.cgi/poky/tree/meta/recipes-devtools/pkgconfig/pkgconfig/disable-legacy.patch

and versions prior to 0.25 have broken sysroot support.
