Add helper function to fixup libtool files

When "libdir" is not the final path where we install the library,
libtool will mess up the relinking process and prepend the global
library directories to the linker search path.

If we fix the libdir path, libtool will insert it into the rpath
in the binary, which is also pretty bonkers.

Maybe, there is a way to do this correctly, but the various GNU
mailing lists, Debian wiki, etc.. could not provide a better
alternative than patching up libtool scripts.
