makefiles: sanitize environment

Compilation needs to generate 'C' locale sorted command file
definitions. To always enforce 'C' sorting rules user LC_ALL
instead of LANG, as  LANG settings can be overuled by
other LC settings like LC_COLLATE and may result into miscompiled
lvm2 binary if locales ordering differs from 'C'.
