I build from a local repository all the time, but don't do it via
mirrors. I simply bbappend the recipe, and change the SRC_URI to
point to a local repo.

i.e. SRC_URI = 
"git:///home/bruce/poky-kernel/linux-yocto-3.10.git/;protocol=file;nocheckout=1;branch=${KBRANCH},meta;name=machine,meta"

If the recipe you are bbappending has patches and other elements, you
can't just clobber it like I did above .. but you get the general
idea.

Cheers,

Bruce
