FPC 2.4.0 had broken return trampolines for signals on EABI. This was  
fixed in 2.4.2, but that version still contains a serious bug in the  
handling of syscalls with 5 parameters or more that causes random  
errors.

You have to move -dFPC_ARMEL from CROSSOPT to OPT. The above command  
will compile an OABI cross-compiler.
