Comment (by ryandesign):

 I did some more research and filed an upstream bug report:

 https://jira.mariadb.org/browse/MDEV-15435

 It appears that `-fwhole-program` is completely pointless for us. New
 versions of clang ignore it (they print a warning that the option is not
 supported), while old versions error out. We could probably just remove
 the flag.

 I'm not clear why we don't see the same error with mariadb-10.1, which
 contains the flag too. Maybe the particular subsection of the build that
 involves this flag is off by default on 10.1 but on by default on 10.2.
