[PD] compiling externals on ARM

[katja]

Actually I think that the library template should work for Linux on
ARM too, as is. Only it does not provide specific optimization flags,
which those ARM boards sorely need for performance. But if it does not
build at all, there may be something else wrong, for example the build
directory structure. Let's not conclude too early that the makefiles
are at fault.
