If you only want to test whether the compiler builds you can do a 
"fullcycle" inside the compiler directory.

If you also want to test whether the RTL compiles you could use dummyas 
in compiler\utils and pass that as AS and compile the RTL for all 
platforms you want to test though that will obviously hide assembly 
problems. Otherwise you'll need binutils for all platforms you want to test.

I myself (as I'm using Windows 10) use the Windows Subsystem for Linux 
where I have installed the binutils for various targets and can compile 
the whole of FPC from the same repository I use on Windows for various 
targets and using QEMU's user space emulation I can even run the testsuite.
