[PATCH] Configure: assorted changes.

[Piotr Sikora]

Hey,
attached patch with a few configure changes for 3rd party libs
that were in my local tree.

I didn't want to spam you with one-line commits, so I squashed
them as one, hopefully that's OK as they are kind of related.

Best regards,
Piotr Sikora

Configure: assorted changes.

Libatomic:
- pass CC to the configure script,
- call "make clean" before rebuild.

OpenSSL:
- pass CC to the configure script,
- call "make clean" only if Makefile exists (allows build from git),
- don't build man pages (25% faster build time).
