autoconf: Unset NO_STH and NEED_STH when it is detected not needed

When configure detects some NO_XXX or NEEDS_XXX is unneeded, unset
this variable (actually set it to empty string).  This allow
autodetection to override the default set in Makefile.

[jc: while at it fixed a thinko in IPv6 detection.]
