[OE-core] [PATCH v2] openssl: Use the c_rehash shell re-implementation for target

[Richard Purdie]

I was asked for my views on this thread.

OE is primarily targeting embedded systems and removing a perl
dependency from target is something we do care about and a significant
win. 

As such I'm tempted to merge this patch in for that reason. The fact
we're successfully using it at rootfs time is a good sign.

I was also made aware that on target ca-certificates is currently
broken by the last change in this area and this patch does in fact fix
that again. This tells us nobody uses it that heavily on target as
nobody noticed. It also means we could do with some better tests :/.

I think the commit message could use some work but IMO this patch
probably is worth it for OE.

I also note with interest that upstream are writing a C version as that
would solve much of this debate once and for all meaning we might not
have to carry this change forever. It would be good if the new upstream
version cared about sysroot style usage...

Cheers,

Richard
