86 <para>Normally, the tooldir (the directory where the executables will
87 ultimately be located) is set to <filename

89 example, x86_64 machines would expand that to <filename
90 class="directory">/usr/x86_64-unknown-linux-gnu</filename>. Because this is
91 a custom system, this target-specific directory in <filename
92 class="directory">/usr</filename> is not required. <filename
93 class="directory">$(exec_prefix)/$(target_alias)</filename> would be
94 used if the system was used to cross-compile (for example, compiling a
95 package on an Intel machine that generates code that can be executed
96 on PowerPC machines).</para>
