Even easier - a temporary change of the PKG_CONFIG_PATH is sufficient, configure
does everything that is needed later on:

address@hidden:~/qemu-test/qemu$ env
PKG_CONFIG_PATH=/home/erik/libusbx/.install/lib/pkgconfig:$PKG_CONFIG_PATH
./configure [...]

where the .install directory was created by a manual call of make install from
libusbx.

Works fine for me.
