mariadb-10.2, mariadb-10.3, mariadb-10.4: 'mutable' and 'const' cannot be mixed

[mav2287 (James)]

Unable to build MariaDB on 10.11 El Capitan. In order to update current working install of mariadb-10.2 @10.2.30_1 additionally 10.3 and 10.4 seem to exhibit the same behavior.

ouput is as follows:

Please add the full log as an attachment. If it's excessively large, you can compress it with bzip2 first.

Please see uploaded main.log

I also tried installing 10.3 and 10.4 ( Not previously installed on this system ) which resulted in what appears to be the same error. My best guess is that what is causing the build to fail with 10.2 is most likely what is wrong with those as well. So if a fix it found it will most likely need to be applied to 10.3 and 10.4 as well.

The 10.11 builder encountered similar errors for ​mariadb 10.2, and errored for ​10.3 and ​10.4 as well.

[chrstphrchvz (Christopher Chavez)]

mariadb-10.5 ​is also affected.

[chrstphrchvz (Christopher Chavez)]

I notice that at least some of these ports ​build successfully on 10.7 where MacPorts' clang 9.0 is used instead of Xcode clang. I have ​opened a PR to avoid compiling with known-non-working versions of Xcode clang (8.2.1 and earlier; the earliest known working version I'm currently aware of is 9.2).
