markers: fix duplicate modpost entry
When a kernel was rebuilt, the previous Module.markers was not cleared. It caused markers with different format strings to appear as duplicates when a markers was changed. This problem is present since scripts/mod/modpost.c started to generate Module.markers, commit b2e3e658b344c6bcfb8fb694100ab2f2b5b2edb0 It therefore applies to 2.6.25, 2.6.26 and linux-next. I merely merged the patches from Roland, Wenji and Takashi here. Credits to Roland McGrath <roland@redhat.com> Wenji Huang <wenji.huang@oracle.com> and Takashi Nishiie <t-nishiie@np.css.fujitsu.com> for providing the individual fixes. - Changelog : - Integrated Takashi's Makefile modification to clear Module.markers upon make clean.
