Subject: CRIS v10: Update rescue Kbuild makefile.
X-Git-Tag: v2.6.25-rc1~40^2~133
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=63e6b9a0b876a287782a706351e0868789673f90;p=linux-2.6

CRIS v10: Update rescue Kbuild makefile.

- Remove old specific targets, use more generic ones instead.
- Use if_changed to avoid creating new images when no change.
  Removes a lot of cruft.
- Use EXTRA_CFLAGS instead of CFLAGS.
