I am doing something similar to what you are doing, see below....
I also needed to create a softlink so that fpc can call ppcrossarm, it
expects to call ppcarm
By using 'INSTALL_UNITDIR' there is no need to copy files at the end.
You will need to do a little tweak in fpc.cfg, after this it is
transparent to handle the different subarchs, at least for arm and
mipsel ;-)
Now I can use fpc to select matching arch/subarch and Lazarus works just
fine.

fpc-cfg change:
# searchpath for units and other system dependent things
#ifdef embedded
-Fu/usr/local/lib/fpc/$fpcversion/units/$fpctarget/$fpcsubarch
-Fu/usr/local/lib/fpc/$fpcversion/units/$fpctarget/$fpcsubarch/*

There is a similar problem with the AVR target having several
subarchitectures. One option I think is to have a subarch defined by
the compiler, then it would be easy to lay out the compiled unit
structure in fpc.cfg according to subarch. I've made an attempt at
adding a subarch define to my local compiler source for AVR, but
haven't developed the idea further. I'm not a compiler dev so there
may be better options.
Subarch directories are imo the best solution, I have a half-backen patch for
this, not yet
finished
though.
I've made a script file (attached) that iterates through the different
subarchitectures
available for the AVR compiler, calls make and then moves the compiled units to
a subdirectory.
I think the logic of this script should be moved to the existing rtl makefile
so that all
subarchitectures for a target gets generated and sorted in one go. Of course
then the default
fpc.cfg ideally needs to be updated to reflect the subarch folder structure for
ARM and AVR.
I'm putting this out there hoping that someone familiar with the topic and
makefile syntax can
help with a patch for FPC.
