It would be useful to know on which ARM/Linux platform you want to run 
your code (board/processor, and if it's an ancient board and/or kernel, 
whether it's ARMEL/EABI or not), and which command line options you are 
using to build FPC.

There is no single ARM/Linux platform, but many different incompatible 
ones (which is one of the reasons there are no provided FPC 
cross-compilers for this "platform".
