29 <para os="s1">EGLIBC's <filename>configure</filename> script checks the
30 version of GCC, and will fail if it's less than 3.4. The next EGLIBC build
31 will use the GCC that will be installed into
32 <filename class="directory">/cross-tools</filename> in the next step.
33 However, in this step only the EGLIBC headers are being installed - no
34 compiling is taking place - so the GCC version isn't important. The
35 following sed removes the dependency of GCC 3.4.x:</para>
