[PATCH] reset LC_MESSAGES to C too

[Andrey Borzenkov <arvidjaar@gmail.com>]

If user locale has non-ASCII translation strings, running grub make
outputs only question marks:

bor@opensuse:~/build/grub> locale
LANG=ru_RU.utf8
LC_CTYPE="ru_RU.utf8"
LC_NUMERIC="ru_RU.utf8"
LC_TIME="ru_RU.utf8"
LC_COLLATE="ru_RU.utf8"
LC_MONETARY="ru_RU.utf8"
LC_MESSAGES="ru_RU.utf8"
LC_PAPER="ru_RU.utf8"
LC_NAME="ru_RU.utf8"
LC_ADDRESS="ru_RU.utf8"
LC_TELEPHONE="ru_RU.utf8"
LC_MEASUREMENT="ru_RU.utf8"
LC_IDENTIFICATION="ru_RU.utf8"
LC_ALL=

make[2]: ????? ?? ???????? `/home/bor/build/grub/docs'
Making all in util/bash-completion.d
make[2]: ???? ? ??????? `/home/bor/build/grub/util/bash-completion.d'
make[2]: ???? `all' ?? ??????? ?????????? ??????.
make[2]: ????? ?? ???????? `/home/bor/build/grub/util/bash-completion.d'
make[1]: ????? ?? ???????? `/home/bor/build/grub'

The reason is, grub Makefile resets LC_CTYPE to C. This makes it
impossible to translate messages into current locale (C at the time
tools are running). Reset LC_MESSAGES to C as well, it is better to
have them in English than do not have them at all.

Problem observed on Linux with glibc 2.17 and 2.15.
