Does the compiler also say "Target OS: Linux for ARMHF"?

If you need -Fu/usr/lib/fpc/2.6.4/units/arm-linux, that means the
configuration file (/etc/fpc.cfg) has not been generated properly. It
should have been generated when you installed fpc.

Secondly, do you have a file called /usr/lib/arm-linux-gnueabihf/crti.o
? That is the file containing the _init and _fini symbols. FPC for ARMHF
will automatically search /usr/lib/arm-linux-gnueabihf/ for that file if
libc is linked and add it to the linker script.

If you don't have that file, install the libc6-dev package (sudo apt-get
install libc6-dev). I would expect the fpc package to depend on that though.
