Fix gdb.rust/simple.rs for more recent compilers

Browse Source 
gdb.rust/simple.exp will fail when run with a recent version of rustc.
This patch fixes the test case so that it will continue to run.

Tested on x86-64 Fedora 28.

I also temporarily backed out the rust-lang.c from
commit 098b2108a2, and verified that
this updated test still would have provoked the original bug.
