Author: aldot
Date: 2007-06-26 09:36:31 -0700 (Tue, 26 Jun 2007)
New Revision: 18945

Log:
- filter out eventual -fPIC -fpic -DPIC flags from the target cflags
  Honor the .config setting for KCONFIG and FORMAT iff not imposed by the target/device. If they are not set in the config, the defaults (zImage etc) still apply.
