The documentation is not up to date. flashrom requires libusb now at
build time because of the inclusion of a libusb-based programmer. You
can turn it off (and thus enable compilation without libusb) by adding
CONFIG_PICKIT2_SPI=no to the command line (for now).

I am only cross-compiling flashrom for windows so I am not sure if that
helps you, but there I am using the newly introduced LIBS_BASE make
parameter to indicate the path containing the include and lib
directories with the respective header and library files like so:

make LIBS_BASE=/home/flashrom/cross-libs/i686-w64-mingw32

The layout within that directory should look like the common unix
layout, i.e. /lib containing *.a, /bin with *.dll and /include with *.h
files.

The PKG_CONFIG_PATH message can be ignored usually. The default will
probably work anyway.
