FWIW, the current new-build and the current old-build both allow you to specify 'make DISABLE_INTREE_EC=yes' and do the right thing. However, currently there is no way to say this using configure. The patch I posted makes configure automatically set DISABLE_INTREE_EC=yes if the directory is not found. The directory is always present in OpenJDK8. However, some Linux distributions prefer to build with ECC disabled due to legal reasons [1], and will remove the directory when they create the OpenJDK8 source tarball. Where they had to delete the directory _and_ set DISABLE_INTREE_EC before, with this patch they just have to delete the directory. If you would like me to add a configure option to control this as well, then I will be happy to add that too. May I do that as a separate patch?
