Commit a9903811bf missed two uses of the
the .gz suffix in the wrapper script and didn't clean the additonal
possibly cached files.

# Makefile for making ELF bootable images for booting on CHRP
|
|
# using Open Firmware.
|
|
#
|
|
# Geert Uytterhoeven September 1997
|
|
#
|
|
# Based on coffboot by Paul Mackerras
|
|
# Simplified for ppc64 by Todd Inglett
|
|
#
|
|
# NOTE: this code is built for 32 bit in ELF32 format even though
|
|
# it packages a 64 bit kernel. We do this to simplify the
|
|
# 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.
|
|
# To make it easier to setup a cross compiler,
|
|
# CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
|
|
# in the toplevel makefile.
