external/pflash: Add script to build all backends

We need to test all the backends when eg. making changes to libflash, to
ensure that something hasn't gone wrong. To encourage developers to do
this, add a script to simplify it.

Patches welcome to detect the specific cross compilers binaries shipped
on your favourite distro.
