Works for me. On the test from bugzilla, I get the expected warning:
strip: Cannot remove symbol  from allocated symbol table 
but ldd is perfectly happy with the result.
I also tried it with a manual "objcopy -R .rustc" beforehand, which I
will probably do in the rpm to prevent that section from even being
saved to debuginfo -- just discard it entirely. Strip still works with
the same warning and a working result.
Thanks for testing. It also has been in Fedora rawhide for some time
now. I pushed it to master.
