Subject: ar71xx: fix wndr3700_board_detect for some NETGEAR WNDR3700v2
There are a few NETGEAR devices which don't terminate the model name in the
ART with a NUL byte, at least some NETGEAR WNDR3700v2. The current awk
expression doesn't match 0xFF bytes, so AR71XX_MODEL contains lots of
trailing 0xFF garbage in this case.
Fix this by matching for the first non-printable character and explicitly
setting LC_CTYPE=C (probably not strictly necessary on OpenWrt, but will
definitely work like this, even when awk supports locales and LANG is set).
