rustc: set crt-static flag

Browse Source 
The crt-static option selects if the C runtime is linked dynamically or
statically into the resulting binaries.

There is a default value of this setting for each platform, but it is
not always what we want. For example, musl targets are assumed to always
have the C runtime linked statically, but we support both.

In practise, this fixes an error in the pkgsMusl.rustc build:
> cannot produce dylib for `rustc_driver v0.0.0 (/build/rustc-1.63.0-src/compiler/rustc_driver)` as the target `x86_64-unknown-linux-musl` does not support these crate types
