parisc: remove arch/parisc/nm

Parisc overrides 'nm' with a shell script. I was hit by a false-positive
error of $(NM) because this script returns the exit status of grep
instead of ${CROSS_COMPILE}nm. (grep returns 1 if no lines were selected)

I tried to fix it, but in the code review, Helge suggested to remove it
entirely. [1]

This script was added in 2003. [2]

Presumably, it was a workaround for old toolchains (but even the parisc
maintainer does not know the detail any more).

Hopefully, recent tools should work fine.
