dev-lang/crystal: Workaround tty corruption in crystal, bug #616256
Patch restores blocking mode of file desriptors in exchange
of potential runtime deadlocks when dealing with stdio.
As it's a potentially invasive patch it's not enabled by default
and is available only under USE=blocking-stdio-hack
