Subject: [PATCH] Makefile: do not override LC_CTYPE
Setting LC_CTYPE=C breaks localized messages in some setups. With only
LC_COLLATE=C and LC_NUMERIC=C, we get almost all we need, except for not
so defined character classes and tolower()/toupper(). The former is not
a big issue, because we can assume that e.g. [:alpha:] will always
include a-zA-Z and we only ever process ASCII input. The latter seems
only affect arch/sh/tools/gen-mach-types, which we can handle separately.
So after this patch the meaning of ranges like [a-z], the behavior of
sort and join, etc. should be the same everywhere and at the same time
gcc should be able to print localized waring and error messages.
LC_NUMERIC=C might not be necessary, but setting it doesn't hurt.
