commit: http://git.buildroot.net/buildroot/commit/?id=c8937ade4bc29fd8a502b8e9cd0b392a7e76fa30
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

The commit 720893b62510438237b9923d744dd079ddb4f67d "openssl: disable
apps for NOMMU" prevented the openssl binary from being built without
MMU in order to fix a build failure without fork(). However, openssl is
designed to support the lack of fork() with -DHAVE_FORK=0, so allow the
openssl binary to be enabled without MMU thanks to this option.
