Subject: Add --kerneldir configure argument
X-Git-Tag: 0.10.0-0maemo1~715
X-Git-Url: http://git.maemo.org/git/?a=commitdiff_plain;h=eac3026225fe7224a1e1c492482b7480df5f36ea;p=qemu

Add --kerneldir configure argument

This allows a user to override the default search path and also makes cross
compilation work a bit nicer wrt KVM detection.
