That error means that something went wrong earlier.  Look upwards at
config.log and you will see somewhere that it tried to do a link test
that fails, typically due to missing or improper crt*.o, and thus it set
the NO_EXECUTABLES flag.  From that point on, the next test that tries
to link something will give that error, but the problem was whatever
test failed originally.  The details should all be in config.log.
