With Ubuntu/Debian:
- apt-get install binutils-arm-linux-gnueabihf

The various binutils executables will be available then as
arm-linux-gnueabihf-*, so you need to use parameter
-XParm-linux-gnueabihf- when invoking the compiler.

If you're using a different Linux distribution, look up a similar package
in your distribution, most bigger distros provide cross-binutils packages
these days for ARM.

You can also build cross-binutils from source, but that's not FPC specific
at all. Among many others, this GCC cross-howto explains how to build a
cross binutils (see chapter 1):

But on the RPi, instead of TARGET=aarch64-linux one has to use
TARGET=arm-linux-gnueabihf, if I'm correct.
