configure: log -I and -L before doing first library check

... for debugging purposes.

this needs to work in every configure run even though the options
(currently) come from qtbase's global scope. this is accomplished by
automatically injecting the test type dependencies declared in the
'builtins' scope (where they generally make no sense whatsoever, because
there are no tests there) into other scopes (the first one that has a
test of the particular type, specifically). we do that *after* the
scope's own test type deps, so it can do its custom stuff first (it can
explicitly activate the required features if it depends on some global
stuff).
