[fpc-pascal] Why can't you cross-compile from x86_64-linux to i386-linux?

I hate cross-compiling because it never works for me, or gives very
unstable executable as end result. But I wanted to cross-compile in a
pinch - which clearly is not a good choice.

I have a ppc386 symlink in the same 'bin' directory as my 64-bit 'fpc'
executable and this is what Lazarus gives me when I changed linking
Target and CPU settings.... I guess there is a big difference between
ppc386 and ppcross386. ;-)

I guess I'll just have to setup a full blown "native" FPC for each
platform I want to support in separate VM's. This clearly seems the
safest and most reliable option (and what I have used to date - but I
don't have a current 32-bit FPC for FreeBSD 9.0 setup, hence my
attempt at cross compiling).

Thanks for responding though... I'm installing FPC from scratch in my
FreeBSD VM now.
