As far as I know, there is no canned way.

I hack otp.mk.in to change the ERL_COMPILE_FLAGS (to cut .beam size)
and run strip from outside the OTP build process (to cut executable size).

Then there's the related problem of "how do I get rid of all the
.beams I never use". xref is a useful tool, but ultimately the process
is mostly manual. The OTP libraries aren't layered.
