makepkg: add libdepends support
The user adds libaries to the depends array without a version. These must end with .so. Example: depends=(glibc libc.so) find_libdepends() looks for ELF files (not symlinks because these could point outside of pkgdir) in $pkgdir, extracts the library sonames the binary links to and outputs depends seperated by spaces. This list contains all libraries needed by the package. Example: libfoo.so=3-64 write_pkginfo() only keeps .so depends with version information and warns the user about unneded ones. Support-by: Thomas Bächler <thomas@archlinux.org> Support-by: Christoph Schied <Christoph.Schied@uni-ulm.de> Signed-off-by: Florian Pritz <bluewind@server-speed.net>
