But wouldn't that apply only to errors that occur during the
configuration step? Or have you observed a situation where a compilation
change triggered by a failing non-essential test caused an error later?

Speaking of which, is there any way to configure flags per package?
Something like /etc/portage/package.flags, where I can configure CFLAGS,
CXXFLAGS and LDFLAGS?
