Re: uname -m and MACHINE_ARCH

I have a package (wip/libmicro) where nearly all build and
scripts use the output of uname -m to generate binaries.

I currently use MACHINE_ARCH, which expands to `uname -p`.

Out of interest, for portability reasons, what would be advised to make
the whole thing more portable, both from an OS and architecture PoV?

Well, I am only missing a wrapper for the "uname -m", but did not manage to find the reasons behind ${ARCH} removal.

What prevents the definition of such wrappers, like an ${HARDWARE_ARCH} as equivalent to `uname -m`?
