Which version of Buildroot are you using ?

Not clear what is happening here. The error log you have suggest that
there is something fundamentally wrong in your Buildroot
setup/installation, but the fact that your build works with
MARIADB_CONNECTOR_C_VERSION = 2.3.7 invalidates that.

So let's take a step back:

 * What is your Buildroot version ?

 * Without your changes, when you do "make clean all", does it build
   successfully ?

 * Then, when you do your changes, and rebuild just the
   mariadb-connector-c package (make mariadb-connector-c-dirclean all)
   what is the complete log ?

Note: you don't need to use make -w --trace, just "make" will give
enough details.

Best regards,

Thomas
