undefined symbol: mjit_init_p

I pulled Ruby trunk on 3 Jul and am now getting errors similar to the
following:

MJIT warning: failure in loading code from
'/tmp/_ruby_mjit_p20781u0.so': /tmp/_ruby_mjit_p20781u0.so: undefined
symbol: mjit_init_p

The pull before that was 4 June and I didn't get the errors. It looks
like this commit may have removed mjit_init_p:

<a href="https://github.com/ruby/ruby/commit/06f54f03039c225c5c0b5d1709865fb4fff02776#diff-75b3ed34ab948aab8de703d073f34a98" title="https://github.com/ruby/ruby/commit/06f54f03039c225c5c0b5d1709865fb4fff02776#diff-75b3ed34ab948aab8de703d073f34a98">https://github.com/ruby/ruby/commit/06f54f03039c225c5c0b5d1709865fb4fff0...</a>

I'm not sure what's referencing the lack of the symbol.

Platform:
CentOS 6, patched
GCC from rpm, 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC)
Autoconf 2.69

Thoughts?

It's not reproducible on my environment and any CI since mjit_init_p
does not exist anywhere in the current trunk, but my guess is that you
didn't execute `make install` and thus you're using an old MJIT
header. MJIT never works without `make install`.

I always build ruby with `make all install` for that reason.
