Sören Tempel ad13725047 makefile: Fix usage error with busybox grep
Busybox grep does not support long options. In fact, the utilized long
options are not mandated by POSIX.1-2008. Using the short options allows
building RIOT on Alpine Linux which utilizes Busybox instead of GNU
coreutils by default.
