Starting trunk's top-level make with the correct options (crossall,
CPU_TARGET, CROSSOPT fot the target flags, etc) and a 3.0.0 should already
result in a native compiler for Aarch64-linux, as the Makefile already does
what you described here (compiling a cross compiler first and then a native
compiler). At the end there should be a ppcrossaarch64.exe and a ppcaarch64
(no .exe!) [Note: I don't know whether the compiler suffix is really
aarch64, as I've never worked with it yet].

There won't be any bootstrap compiler however until the next major version
containing the new platform is released as trunk is a moving target (it can
happen from one revision to the next that trunk can no longer be compiled
by the previous revision).

(as I remember correctly: main and lcl/interfaces had no aarch64-linux
target).

You should raise this issue either on the Lazarus mailing list or the bug
tracker.
