doc: make i18n man and html
Allow overwrite LANGUAGE and LC_ALL make variables, for make i18n man and html.
After this patch, we can make i18n man and html by following command:
$ make clean all LANGUAGE=ja
$ "$TESTDIR/hghave" pyflakes || exit 80
$ cd "`dirname "$TESTDIR"`"
run pyflakes on all tracked files ending in .py or without a file ending
(skipping binary file random-seed)
$ hg manifest 2>/dev/null | egrep "\.py$|^[^.]*$" | grep -v /random_seed$ \
> | xargs pyflakes 2>/dev/null | "$TESTDIR/filterpyflakes.py"
