mrustc: init at 0.9 mrustc is mostly patched to use shared LLVM sources but still uses in-tree source for compiler-rt from LLVM 7. This needs to be patched to compile under glibc 2.31 or later. It's easy enough to reapply all our compiler-rt patches here.

treewide: add meta.mainProgram to packages with a single binary The nixpkgs-unstable channel's programs.sqlite was used to identify packages producing exactly one binary, and these automatically added to their package definitions wherever possible.
