Import slibtool-0.5.12 as devel/slibtool

slibtool is an independent reimplementation of the widely used libtool,
written in C. slibtool is designed to be a clean, fast, easy-to-use
libtool drop-in replacement, and is accordingly aimed at package authors,
distro developers, and system integrators. slibtool maintains compatibility
with libtool in nearly every aspect of the tool's functionality as well as
semantics, leaving out (or turning into a no-op) only a small number of
features that are no longer needed on modern systems.
