[arch-dev-public] [signoff] pciutils 3.1.7-4

Please signoff for both architectures. This update cleans up the PKGBUILD in a way that uses all possibilities that are present in the Makefile: - PREFIX="$pkgdir/usr" is replaced by using DESTDIR - install-lib target is used instead of copying files around This release contains both shared and static libraries. As I don't have any overview of what still needs this static library (default is to ship only static), I decided to keep it in for a while. As we're using the install-lib target, a .pc file is also shipped now.
