I guess you have created 'local arch=' for a reason.

[no idea where you plan to use it, but] 'uname -m'
is fragile in croscompiler environments which you
seem to have touched in description.

'uname -m' usually breaks when you chroot to 32bits
on amd64 and don't use 'linux32 chroot'.

But again, I have no idea what MACHINE_CPUARCH is.
Switch based on ${ARCH} or ${CHOST} and overridable
by ${CTARGET} might fit you more.
