[BusyBox] buildroot warnings: "overriding commands for target ..."

[Sam Robb]

After a recent svn update, when doing "make world" with
buildroot, I see the following warnings:

package/tcl/tcl.mk:60: warning: overriding commands for target `less-
dirclean'
package/less/less.mk:49: warning: ignoring old commands for target
`less-dirclean'
package/xorg/xorg.mk:56: warning: overriding commands for target
`/home/sam/depot/trunk/netfilter/buildroot/build_i386/root/usr/X11R6/bin//Xfbdev'
package/tinyx/tinyx.mk:101: warning: ignoring old commands for target
`/home/sam/depot/trunk/netfilter/buildroot/build_i386/root/usr/X11R6/bin//Xfbdev'
package/xorg/xorg.mk:68: warning: overriding commands for target
`/home/sam/depot/trunk/netfilter/buildroot/build_i386/root/usr/lib//libX11.so.6.2'
package/tinyx/tinyx.mk:116: warning: ignoring old commands for target
`/home/sam/depot/trunk/netfilter/buildroot/build_i386/root/usr/lib//libX11.so.6.2'

Do these warnings represent a work in progress?  I'm happy
to look into this and try and figure out how to deal with
this, but I don't want to duplicate someone else's work.
