Makefile: set LC_CTYPE, LC_COLLATE, LC_NUMERIC to C

There are a number of common Unix constructs like character ranges in grep/sed/awk which don't work as expected with LC_COLLATE set to other than C. Similarly, set LC_CTYPE and LC_NUMERIC to C to avoid other nasty surprises. In order to make sure these actually take effect we also have to clear LC_ALL. Signed-off-by: H.
