Build system is broken on macos

[haampie]

./configure --prefix=/something
make
make install

on darwin, I'm ending up (a) without pkg config files and (b) with an incorrect symlink:

$ ls -l lib/
librhash.1.dylib
librhash.so.1 -> librhash.1.dylib

Shouldn't it be librhash.dylib -> librhash.1.dylib?

I completely agree with #65, cause it's a major pain to build such a trivial package...
