Looks like some buffer is printed twice (starting at the second --plugindir)
and this includes all *bytes* from the buffer, ignoring zero termination.
Redirecting this to a file (or piping through hd) does not give the the duplicate
--plugindir setting, but a lot of \0 bytes (and three non-\0 bytes) at the end.
Running mariadb_config with some arguments emits similar trailing binary crap.

This breaks the rmysql configure script.


While you are it it, please filter out -fdebug-prefix-map=* from the cflags.
