OSX makefile patches

[kyngchaos]

some general cleanup of the OSX framework build. Changes and issues addressed:

• the lib rename and install_name_tool steps were moved to the more appropriate install-lib target. What was in install-actions was really specific to the libtool build.

• handle cases of libtool installed binaries vs. symlinks for which lib to rename.

• install correct lib for ld-shared build.

• remove framework bits for static lib build - frameworks can't be static libs.

Configure needs a change to disable a framework build if both static lib and framework build are specified. Printing a warning that both were specified but are incompatible would be helpful.

William,

I have applied your patch without much review other than confirming it doesn't break anything :)
