WAF config.h differences compared with autoconf on FreeBSD

[Timur I. Bakeyev]

Interesting...

Well, checks for libmd(5) and FAM plainly don't exist in in WAF. This part
is easy :)

rl_event_hook check gives me different results, I see it originates from
libreplace checks in WAF, but in autoconf it is part of source3/.

I have no idea what ATTRIBUTE_COLD is.

And the check behind FreeBSD statvfs() is entirely obscure for me. I
couldn't figure out what does it really checks for?
FreeBSD has both statfs() and statvfs(), the last one is a wrapper around
former one. But the check is saying about some struct statfs fields,
although referencing to stavfs()... Need help!

With regards,
Timur Bakeyev.
