rdoc seems to be written to run without gem. However,
some internal code still does not check for gems presence.
With a small patch, rdoc can run without gems.

ruby, by default, try to load gems on start. If not
present, it fails. As gems brings many deps, this make ruby
unsuitable for routers limited resources.

ruby can avoid to load gems with the option "--disable-gems".
So, a wrap script in the place of /usr/bin/ruby adds this option
if gems are not found.

Also add vendor/site directories

Docs are not currently packaged. So, there is no need to install
them. Also, doxygen have some problem with the usaged of git in
build_dir as it takes ages running git commands on every file.
Disabling the docs reduces the compilation time.

- build ruby/host extensions as static,
  - remove dependency on gmp/host

libgmp.so is needed for miniruby, that is compiled in host.
Using PKG_BUILD_DEPENDS=gmp/host eventually compiled gmp/host
before ruby/host. However, when this did not happened, build
failed. Using HOST_BUILD_DEPENDS=gmp/host seems to be the
correct way to require it.

This commit imports the old Makefile from old openwrt feeds.
Also, the package was updated to the latest version.

The new version was tested in a VM with no aparent problem.
No patches are needed.

I added myself as maintainer. If possible, I would like to gain
commit access.
