It turned out, it wasn't needed. So I made a really quick hack this
morning, and now FPC builds for and semi-works on Haiku/x86_64...

There seems to be something wrong with the signal setup so strace is used
to hide a fatal error... Also file handling doesn't really work now. But
even to get to this level in a few hours was nice.

The patch is of course still a bit of a mess, especially the RTL part, but
I can commit the "trivial" parts of it to SVN, if you have nothing against
it? Like adding the target to the compiler at least. (This question is to
Olivier primarily, as he's the Haiku maintainer.)

Cheers,
