Only the native tools will be installed there, so this will be empty
on a crosszipinstall.

lib/fpc/2.5.1/ppcrossarm is the crosscompiler you are looking for.

ppcarm is for native compilation, so if you want that, don't use
crosszipinstall, just use zipinstall.

This is so that the compiler cycle doesn't do wpo (which adds another
couple of cycles).  I tend to use it because my computer is slow (and
I am impatient).  wpo should give better performance/size, though.

This compiles the rtl/packages with -CfSOFT, which may be the default
for an armel compiler, I'm not sure.
