    gccrs: Adjust unknown macro error message
    
    gcc/rust/ChangeLog:
    
            * resolve/rust-early-name-resolver-2.0.cc
            (Early::visit): Adjust error produced when macro resolution
            fails.
            * resolve/rust-early-name-resolver.cc
            (EarlyNameResolver::visit): Likewise.
    
    gcc/testsuite/ChangeLog:
    
            * rust/compile/macros/mbe/macro43.rs: Adjust expected errors.
            * rust/compile/macros/mbe/macro44.rs: Likewise.
            * rust/compile/nested_macro_use2.rs: Likewise.
            * rust/compile/nr2/exclude: Remove entries.
