Currently you have to override a bunch of paths to use firmware-devel
when building the installer. This changes that, and adds a new
FIRMWARE_PROFILE envvar that can be used to fix both rootshell and
rayhunter-daemon paths at the same time.
There is now also a new cargo command for building rootshell, similar to
how building the daemon firmware works.
I'm not sure what to do with make.sh. I have personally never used it.
Support more platforms by using a the soft float musl target for
aarch32/armv7/v8. The installer is not performance bound by floating
point operations.
rustc -C strip=debuginfo leaves the symbol table intact, meaning
RUST_BACKTRACE=1 on the installer still produces helpful output.
This significantly reduces the binary size, eg the amd64 installer goes
from 93M to 21M. Stripping the symbol table only reclaims a further ~2M.
