[fpc-pascal] Why can't 64bit FPC cross-compile 32bit

Ah yes. Sorry, I did not notice the '32' at the end.

Ummm... I'll go read the wiki and buildfaq again. I'm a bit confused
though. When I switched computers and moved from 32bit Linux to 64bit
Linux, I used my 32bit Linux FPC 2.2.5 and cross-compiled a "what I
thought was a 64bit FPC", and have been using that ever since as my
64bit FPC?

So how is what I am using now, not a 64bit FPC? Linux seems to report in
correctly as 64bit? Below is what I was left with after I did the
cross-compile from 32 -> 64 bit.

$ file /opt/fpc_2.2.5/bin/fpc
fpc: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically
linked, for GNU/Linux 2.4.0, not stripped

$ file /opt/fpc_2.2.5/lib/fpc/2.2.5/ppcx64
/opt/fpc_2.2.5/lib/fpc/2.2.5/ppcx64: ELF 64-bit LSB executable, x86-64,
version 1 (SYSV), statically linked, for GNU/Linux 2.4.0, not stripped
