Subject: [PATCH] mjit.c: another try for fixing solaris build

Reverted r62192 and added another try.
I prepared Solaris environment but I couldn't reproduce the RubyCI build
failure. So I'm testing on trunk.

I found the following article and it fixed the same problem with passing
`-D__EXTENSIONS__`. So this commit defines `__EXTENSIONS__` for Solaris.
