Subject: [PATCH] Also compile rustc_driver as rlib

This reduces the amount of patching necessary to get rustc working in
environments where dynamic linking is not possible like wasm, miri or
some niche OSes. There is still a single line patch necessary for miri
to get the sysroot location (a future PR I have planned would as a side
effect likely remove the need for this patch). For wasm some more
intrusive patches are still necessary to disable thread usage.

We will still only ship it in rustc-dev as dylib (all rlibs are
filtered) and given that it is an empty crate, it shouldn't have any
noticable size or compile time impact on building rustc.
