An alternative approach to show how much cleaner the pure pkg-config way is. This changes the discovery procedures for libusb-1.0 and libusb-0.1, making them depend on pkg-config being properly installed and configured, including the necessary build host configuration for the cross-builds (see http://www.flameeyes.eu/autotools-mythbuster/pkgconfig/cross-compiling.html ) It should make it possible to compile OpenOCD without changes and extra effort on GNU/Linux, FreeBSD users would need to supply a .pc file for their libusb implementation or add LIBUSB1_LIBS and LIBUSB1_CFLAGS to the configure environment.
