have you got my mail with attached Mkefile fixes/ patches
& new mkbuild.pl ?
everything works here both with $(objtree) == $(srctree) or with different
obj tree
and about aic7xxx in different objtree -- in vanilla you have to disable
"build firmware with kernel build" (or smth similar) it's fixed in my next
tarball
selinux is broken in different obj tree
