[Skiboot] [PATCH 2/2] external/pflash: Add script to build all backends

[Joel Stanley]

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.
