[PATCH] buildroot: improve git submodule handling for packages=0A=

[Darik Horn]

=0A=
Move the `--recursive` switch from `git clone` to `git submodule`=0A=
so that submodules are cloned for upstream branches where the=0A=
PKG_SOURCE_VERSION commit-ish has a different .gitmodules=0A=
configuration than the repository default.=0A=
=0A=
This is, for example, required when the master branch for a source=0A=
package does not use submodules, but its topic branch for OpenWRT=0A=
does.=0A=
=0A=
This changes the buildroot dependency from git-1.6.2 to git 1.7.12.2,=0A=
which was released September 2012.=0A=
