Kevin, I'd love to support your stance and use GCC. However, there are
reasons why we will need to consider Clang for e.g. Ruby:

And the reason is not even that upstream favors Clang. The situation is
unfortunately not just black and white.
Looks like the best solution there is to disable PCH support in the Ruby
JIT.
It is best solution if your objective is to use GCC. The other best
solution might be to disable GCC hardening (and that is the current
state in Fedora just FTR). But if your objective is hardening as well as
fast execution, disabling PCH support has potentially so high
performance cost that it turns Ruby JIT slower then the execution
without JIT.
