check_config: request at least 1 builtin EC alg if there is at least 1 builtin curve

Browse source 
This slightly changes the previous requirement. Instead of enabling
ALL builtin EC algs when there is at least 1 built in curve, we ask
for at least one built alg if there is at least one builtin curve.

This relaxes the previous check while still keeping the base idea:
there must be a reason for which builtin curves are included into
the build.
