QtWebKit builds its own copy of leveldb [1] (as a third-party) if the system does not provided it (i.e. buildroot). It builds it differently and this is the origin of that issue. Instead of using the Makefile provided by leveldb [2], QtWebKit uses qmake to build that library [3]. The missing symbol issue happens because the symbol leveldb::NewMemEnv is bundled in the static library libmemenv.a (aside libleveldb.so). This static library consists of this single symbol which is like an extra that is built but *NOT* shipped by default at installation in the staging directory. Unfortunatly, that symbol is required later by WebCore [4]. The copy built by QtWebKit is an all-in-one library including both libleveldb and libmemenv; thus QtWebKit links against libleveldb only. Also, the linker finds the buildroot's copy first (not the third-party): that explains why it is complaining about a missing symbol. That copy does not have the symbol leveldb::NewMemEnv. Fortunatly, QtWebKit provides a facility to link against the system leveldb package. The qmake flag WEBKIT_CONFIG+=use_system_leveldb tells Qt5WebKit to link against libleveldb *AND* libmemenv [5]. To fix that issue, this commit selects the package leveldb that now installs the libmemenv static library and its header. It ensures that QtWebKit has everything it needs to be built. It also sets the appropriate qmake configure flags to tell QtWebKit to use the leveldb copy built by buildroot instead of the bundled one.
