New description:

 mariadb-10.2 finds and uses a number of things if present, though it does
 not declare dependencies on them:

  * pkg-config
  * boost
  * bzip2
  * cracklib (crack.h)
  * gdb (bfd.h)
  * git
  * kerberos5 (GSSAPI)
  * ~~libxml2~~
  * lzo2
  * openssl
  * pcre
  * snappy (snappy-c.h)
  * xz (liblzma)
  * and something do with with ODBC (`ODBC_OK`)

 One or more of these is causing the build to fail for me, unless I use
 trace mode. The port should declare dependencies on whichever of these it
 wants to use, and add flags or whatever to prevent the use of the others.

 I did not test other mariadb versions but assume at least some of this
 applies to them too.
