I know repository PKGBUILDs are typically built in a clean chroot, so cached builds make no difference there, but then neither do unquoted srcdir/pkgdir. It is still not helpful to people who e.g. check out a PKGBUILD from svntogit and rebuild it locally for any of a number of reasons to have unpredictable behavior due to assumptions about always building in a clean chroot. So I think maybe we should still (or start?) specifying this.
You don't need to build in a clean chroot to prevent this from happening, you just need to make sure you clean up your build dir before rebuilding after having changed the build flags, which IMO is a reasonable assumption to make.
