[patch] Makefile: Unexport LANG

[Simon Horman]

The recent changes to setting and unexport various LC_ variables
produces a problem on my system (Debian sid).

$ locale
LANG=ja_JP.utf8
LANGUAGE=ja_JP.utf8
LC_CTYPE="ja_JP.utf8"
LC_NUMERIC="ja_JP.utf8"
LC_TIME="ja_JP.utf8"
LC_COLLATE="ja_JP.utf8"
LC_MONETARY="ja_JP.utf8"
LC_MESSAGES="ja_JP.utf8"
LC_PAPER="ja_JP.utf8"
LC_NAME="ja_JP.utf8"
LC_ADDRESS="ja_JP.utf8"
LC_TELEPHONE="ja_JP.utf8"
LC_MEASUREMENT="ja_JP.utf8"
LC_IDENTIFICATION="ja_JP.utf8"
LC_ALL=ja_JP.utf8

Without this patch:
$ make
make[2]: ??: ?? make ? -jN ?????????: jobserver ??????????.
make[2]: ??: ?? make ? -jN ?????????: jobserver ??????????.

With this patch:
$ make
...
make[2]: warning: -jN forced in submake: disabling jobserver mode.
