Well, see the ECL manual, Sect. 3.1.1.2:
https://ecl.common-lisp.dev/static/manual/System-building.html#Native-FASL
It's a basically a dynamic shared library. On Linux I can do

$ ldd local/lib/ecl/maxima.fas
linux-vdso.so.1 (0x00007ffd17c88000)
libecl.so.21.2 => /home/dimpase/work/software/sage/local/lib/libecl.so.21.2 (0x00007cb5df721000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007cb5df5c5000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007cb5df3f1000)
libgmp.so.10 => /lib/x86_64-linux-gnu/libgmp.so.10 (0x00007cb5df370000)
libgc.so.1 => /lib/x86_64-linux-gnu/libgc.so.1 (0x00007cb5df2f8000)
libffi.so.7 => /lib/x86_64-linux-gnu/libffi.so.7 (0x00007cb5df2ec000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007cb5df2c8000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007cb5df2c2000)
/lib64/ld-linux-x86-64.so.2 (0x00007cb5e06d2000)

I think you don't need any of these, except maxima.fas

I don't think there is anything provided by Maxima build system in this
respect (it's highly lisp-system dependent, after all).
One has to copy maxima.fas into /usr/local/lib/ecl/
I suppose OpenBSD ports build system has a way to do this, so that
it's correctly gets uninstalled, too.

- yes, there is a port, as I wrote.

I think for Maxima developers sbcl is the primary lisp system,
and many Linux distros by default ship Maxima built with sbcl.
