During the final link we get errors like this:
.../4.9.4/ld: warning: hidden symbol 'sqlite3_temp_directory' in obj/.../sqlite.sqlite3.o) is referenced by DSO .../usr/lib/libsoftokn3.so
.../4.9.4/ld: error: treating warnings as errors
collect2: error: ld returned 1 exit status

Use chromium.bb solution to not treat linker warnings as errors.
