Renamed internal variable LANG (the language of the man pages currently
being processed) to MANLANG in order to avoid screening global LANG
variable which defines current locale. As the result, got rid of Perl
man2hlp warnings about incorrect locale on build.

The man2hlp program is build using the target compiler. The
resulting executable therefore does not work on the build host.
Since the man2hlp program is needed during compile time, the build
will fail.
Moved man2hlp into separate subdir
