Trying to build on a fedora system I got:

stage0/rustc: error while loading shared libraries: librustrt.so: cannot enable executable stack as shared object requires: Permission denied

Seems like we should be able to support Fedora before we do a release

To be more specific, this is most likely because of an SELinux policy. Fedora just ships with SELinux and policies enabled by default if memory serves correctly. On a minimal (dev-tools only) 32-bit fedora installation, you can run the whole testsuite without issue.

Curiously I couldn't find very exact reasoning as to why librustrt.so was compiled with an executable stack, but the other libraries weren't. It Just Is, and it's the only problematic file (rustc, librustllvm.so etc aren't affected.) Might be a fedora-specific thing?

Either way I've fixed this in a branch with a linker flag. It doesn't seem to hurt anything. It'll need to be pulled and snapshots will need to be registered, so builds on SELinux-enabled machines can work out of the box.

Fix glibc 2.26 incompatibilities rust-lang#788

Hopefully the `xlocale.h` → `locale.h` change won't break something else somewhere...
