No it's not different: the four failures are issues 37131, 49851 and
50993, and sysroot-crates-are-unstable. The latter uses a python script,
which explicitly requires python2.7.

As I noted earlier, fedora have a patch for python3 for (I think) only one
of the rust files. Somebody, probably Thanos, pointed out that some of the
rustc scripts specify 2.7 (I think) - can't find the mail in the archive,
it was probably early this month.
Well, this seems to work for this version of rust. Fedora's patch does not
seem to be needed. It is in a lldb_something file, and I do not think our
build makes lldb usable. I'll try building firefox and let you know if it
works. Note that if changing the python version is enough to generate
SIGSEV, it means that there are severe flaws in the build system... The
python scripts are supposed to run compilation commands, not to define
memory locations...
