  <para>We will need to setup target specific flags for the compiler
  and linkers. You can choose the appropriate BUILD32 and BUILD64
  from the table at the bottom of the page.</para>

<screen><userinput>export BUILD64="[BUILD64 entries]"
export GCCTARGET="[GCCTARGET entries]"</userinput></screen>

  <para>Lets add the build flags to <filename>~/.bashrc</filename> to
  prevent issues if we stop and come back later.</para>

<screen><userinput>echo export BUILD64=\""${BUILD64}\"" &gt;&gt; ~/.bashrc
echo export GCCTARGET=\""${GCCTARGET}\"" &gt;&gt; ~/.bashrc</userinput></screen>

  <para>The following table gives the entires for different Sparc 64 capable
