Fixes for sharing a build tree between Windows + Unix

Rename modules/RELEASE.local to RELEASE.<host>.local
Modify all submodule configure/RELEASE files to include that, and
update the template configure/RELEASE file to match.

Install Perl *ModuleDirs.pm files into bin/<host> since they contain
absolute paths which may be different on different host arch's.
Scripts that need a ModuleDirs module have been adjusted to look in
their bin/<host> directory for it.

Some additional submodule updates were also incorporated.
