changing 'configure' options for testing

In addition to the code Ken just provided, he and others have helped me
with some test-related "protection" code, so that in addition to a
+tests variant, there is the following section of code (I usually place it
after any build-related sections, and before any destroot-related sections,
in order to keep my portfiles laid out in the same order as the port

pre-test {
    if {![variant_isset tests]} {
        ui_error "'tests' variant must be activated to enable test support"
        error "Please enable the 'tests' variant and try again"
