Have you tried building with -g1? That causes less debuginfo and less
memory use.

cross-compilation tend to be very painful and require a lot of hand-
holding, so its not an area i would walk into lightly.

You would have to start with building something like an cross-build
SDK. Probably an aarch64 runtime with compilers targeting arm, so that
you can also run the resulting binaries (as needed in many configure
scripts, etc). Then you need to figure out how to make each individual
component cross-build, which is going to require research for each one.
