[klibc] builtin: Clear LC_ALL in mkbuiltins

In mkbuiltins LC_COLLATE is set, but since "The value of the LC_ALL
environment variable has precedence over any of the other environment
variables starting with LC_"
(http://pubs.opengroup.org/onlinepubs/7908799/xbd/envvar.html), this
has no effect when LC_ALL is set.

This breaks when having e.g. LC_ALL=en_US.UTF-8 during make, which
causes the test case
    dash -c :
to fail, probably due to broken ordering in builtins.c. The patch
corrects that by clearing LC_ALL.
