commit: https://git.buildroot.net/buildroot/commit/?id=8488c0eeeb8c609aec053a7395ea7ddb94ef3152
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Without defining LEVELDB_HAS_PORT_CONFIG_H port/port_config.h will not
be included:
https://github.com/google/leveldb/blob/master/port/port_stdcxx.h#L8
which breaks endian detection. Add the define to our memenv patch to fix
building with gcc < 5.
__has_include was added in gcc5: https://gcc.gnu.org/gcc-5/changes.html
