Runtime dependencies not required for building

Some packages I maintain have a lot of runtime dependencies that are not required at build time (this is common for packages which only ship scripts and have no tests). When building on a clean chroot, I have to wait for hundreds of megabytes in packages to be copied and installed. This is rather inefficient, since these are not required. However, the `makedepends` ARE required in this case, but there is no overlap. I'd like some way to indicate that a PKGBUILD does not require its runtime dependencies for building the package. Perhaps something like `options=(!depends)` I'd like to hear feedback on this, thoughts? -- Hugo Osvaldo Barrera
