Makefile always rebuilds the libraries

[d33tah]

This is probably an easy fix - I used to find myself hacking preeny for my own needs quite a lot once and I found it a bit annoying that "make" would try to rebuild all of the libraries even if I changed just one. Tested on Fedora 21.

Unfortunately, I don't have the cycles to look into this at the moment, but I'd be happy to take a PR if someone does :-)

Here's a partial fix that doesn't remove the symlinks on "make clean":

diff --git a/src/build_so.sh b/src/build_so.sh
index dc2e1f1..d6386ea 100755
--- a/src/build_so.sh

Ah, but this way it won't support building multiple architectures in the same checked out repository :-(

[d33tah]

What's your workflow? Perhaps this should be done by "make install"?

[zardus]

I think just removing the move from build.sh and having it done by "make dist" would be perfect, actually. Good idea!

[zardus]

Ok, I ended up rewriting the whole makefile so that we don't need build_so.sh anymore.

Doing make from the top-level dir will still blow the libs away (I want to avoid confusion between architectures when cross-compiling), but running make in src will have the expected behavior. Let me know if that works for you.
