Compiling libgit2 with libssh2 for iOS

I've got this working but it does introduce some more dependencies:

1. libssh2: git://git.libssh2.org/libssh2.git
2. autoconf: git://git.sv.gnu.org/autoconf
3. automake: git://git.savannah.gnu.org/automake.git

Should I go ahead and open a pull request that includes these dependencies as submodules?
