 #       bootloader and increase compatibility with OpenFirmware.
 #
 #       To this end we need to define BOOTCC, etc, as the tools
-#       needed to build the 32 bit image.  These are normally HOSTCC,
-#       but may be a third compiler if, for example, you are cross
-#       compiling from an intel box.  Once the 64bit ppc gcc is
-#       stable it will probably simply be a compiler switch to
-#       compile for 32bit mode.
+#       needed to build the 32 bit image.  That's normally the same
+#       compiler for the rest of the kernel, with the -m32 flag added.
 #       To make it easier to setup a cross compiler,
 #       CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
 #       in the toplevel makefile.
