Description
When building bundled MariaDB 10.4.7 with latest storage engine Mroonga http://mroonga.org/ , it causes "error LNK2001: unresolved external symbol log_10_int". [1]
It seems that it requires MYSQL_PLUGIN_IMPORT on Windows.
Here is the patch to fix this issue.

Here is the recipe to build latest one. https://github.com/mroonga/mroonga/blob/master/appveyor.yml
The brief instruction is the following:
1. remove storage/mroonga and replace it with latest cloned mroonga (https://github.com/mroonga/mroonga/blob/master/appveyor.yml#L51)
2. exec cmake .. -G "Visual Studio 14 2015 Win64" -DMRN_GROONGA_EMBED=OFF -DMRN_GROONGA_NORMALIZER_MYSQL_EMBED=OFF -DGRN_WITH_MRUBY=ON for configuration (https://github.com/mroonga/mroonga/blob/master/appveyor.yml#L90)
3. exec cmake --build . --config RelWithDebInfo (https://github.com/mroonga/mroonga/blob/master/appveyor.yml#L94)
In Mroonga, it seems that log_10_int is indirectly referenced. (maybe, not confident at all)
1. https://github.com/mroonga/mroonga/blob/master/ha_mroonga.cpp#L12494 uses Field_timestamp_hires
2. Field_timestamp_hires's constructor call sec_part_shift
which is defined https://github.com/MariaDB/server/blob/10.4/sql/field.h#L3253.
3. sec_part_shift uses log_10_int
https://github.com/MariaDB/server/blob/10.4/include/my_time.h#L221
How do you build with Mroonga , if mroonga does not build on Windows, i.e it is disabled via CMake.
