I changed it to "parisc: remove arch/parisc/nm" Applied to linux-kbuild. Thanks for the ack.

Parisc overrides 'nm' with a shell script. I was hit by a false-positive error of $(NM) because this script returns the exit code of grep instead of ${CROSS_COMPILE}nm. (grep exits with 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.
