63 <para>Libtool tends to do the wrong thing when building for multilib,
64 at least on the non-default size(s) of architecture. The causes of
65 these errors are not well understood and they can appear, or disappear,
66 as a result of apparently innocuous other changes in the build. In
67 this version of the book, one of the tests (pdemo-make) fails to link
68 because it tries to link the 32-bit objects against 64-bit system
69 libraries. This option enables the test to succeed without impacting
70 the other tests (compare the common alternative fixes of
71 <literal>LD="gcc ${BUILD32}"</literal> which causes far fewer tests
72 to be executed, and configuring with
73 <literal>LDFLAGS='-L/lib -L/usr/lib'</literal> which in this case
74 causes other tests to fail.)</para>
