[perl #53418] mk_language_shell.pl does not create folders outside of the language folder

Fixed in r27390.  The step for automatically creating the makefile only
works for things in the languages/ subdirectory, so I modified
mk_languages_shell.pl to only attempt the reconfigure if a path wasn't
given.

Thanks,

Pm
