1.9.x has a brand new unix rtl, most calls are now in baseunix/unix and 
prefixed with "fp"

For urgent 1.0.x legacy, the 1.0.x linux unit is available in 1.9.x as
"oldlinux", however while 100% the same as 1.0.10's, oldlinux is not
entangled with system anymore, and this might cause small incompabilities.

For background info, see:

The path where the compiler can find the RTL is in fpc.cfg. So it can't
find system because you specified -n

This means you will have to add the path to your desired RTL manually with
-Fu (check the -Fu line in your fpc.cfg, the one with an asterisk at the end)
