$startdir is also useful for upstream if they want to maintain a
PKGBUILD in their devel repo and build arch packages themselves.

This is assuming that $srcdir or $pkgdir doesn't always mean
$startdir/src and $startdir/pkg. Otherwise one of those vars could be
used.

Example:

files tree:
	Makefile.am
	configure
	packaging/
		archlinux/
			PKGBUILD
		debian/
		fedora/


build() {
	cd $startdir/../..
	./configure
	make
	make install
}
