Maybe via /etc/gai.conf:

,----
| # precedence  <mask>   <value>
| #    Add another rule to the RFC 3484 precedence table.  See section 2.1
| #    and 10.3 in RFC 3484.  The default is:
| #precedence  ::1/128       50
| #precedence  ::/0          40
| #precedence  2002::/16     30
| #precedence ::/96          20
| #precedence ::ffff:0:0/96  10
| #
| #    For sites which prefer IPv4 connections change the last line to
| #
| #precedence ::ffff:0:0/96  100
`----

Changung the preference of "::ffff:0:0/96" to "100" will prefen IPv4
over IPv6.

This is of course global for the server this is set on, so use with
caution.
