leveldb: fix checking for SSE flag
The build_detect_platform-Check-for-__SSE4_2__.patch tries to use fgrep with pipe to get the SSE flag. But actually it would fail with error: fgrep: /tmp/leveldb_build_detect_platform-cxx.25886: No such file or directory That means it can not get the correct SSE flag. We should make sure the fgrep command runs after g++ command has finished and redirect the stdout and stderr to /dev/null to avoid make error: Makefile:18: *** missing separator. Stop.
