If you want to cut out commands, you need to edit the u-boot
configuration file.  See the README file around line 549.
<http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;f=README;h=09eb76fe4528dfedca027b119ac760fce2570e35;hb=HEAD#l549>

Deleting .o files isn't going to be successful because make will simply
rebuild them.
