Don't build extensions for cross rubies.

The extension libraries of the ruby stdlib are not required to cross build binary gems. They just waste compilation time and disk storage. The option "--with-ext=" is supported since ruby-1.9.2, but ruby-1.8.7 just ignores this option. I verified that the cross ruby-build and building binary gems succeeds with the following ruby versions: ``` sh rake-compiler cross-ruby VERSION=1.8.7-p374 HOST=i586-mingw32msvc rake-compiler cross-ruby VERSION=1.9.3-p550 HOST=i586-mingw32msvc rake-compiler cross-ruby VERSION=2.0.0-p645 HOST=i686-w64-mingw32 rake-compiler cross-ruby VERSION=2.0.0-p645 HOST=x86_64-w64-mingw32 rake-compiler cross-ruby VERSION=2.1.6 HOST=i686-w64-mingw32 rake-compiler cross-ruby VERSION=2.1.6 HOST=x86_64-w64-mingw32 rake-compiler cross-ruby VERSION=2.2.2 HOST=i686-w64-mingw32 rake-compiler cross-ruby VERSION=2.2.2 HOST=x86_64-w64-mingw32 ``` The options '--without-tk' and '--without-tcl' are obsolete since ruby 1.8.7. I already use this patch as part of the [rake-compiler-dock](https://github.com/larskanis/rake-compiler-dock) .
