Correction. I misunderstood what was being done here. This forcibly 
set/clears the make variable based solely on the existence of a directory:

test -d "${SRC_ROOT}/jdk/src/share/native/sun/security/ec/impl"

It doesn't expose a configure option for this. This may be perfectly 
fine but the person who wrote the original TODO comment needs to verify 
that.
