----------
<p>The following should be sufficient to configure multilib Mesa</p>

<code>./configure CC="gcc -m32" CXX="g++ -m32" --build=i686-pc-linux-gnu
--host=i686-pc-linux-gnu ...</code>
----------

You should also definitely mention here pkg-config.  E.g. state it as:
In addition to specifying correct PKG_CONFIG_PATH for the target architecture,
following should be sufficient...

Also, "--host" option is redundant, according to Autoconf manual it defaults to
same as "--build" i.e. you need to specify it only if it differs from --build.
