One idea that I have, is for the make file that is genreated for the an
external output directory, if we could preserve the the value of 
BR2_EXTERNAL
as follows. I don't think my logic is fully there but there is more of a 
sudo implementation:

diff --git a/support/scripts/mkmakefile b/support/scripts/mkmakefile
--- a/support/scripts/mkmakefile
+++ b/support/scripts/mkmakefile
@@ -27,6 +27,7 @@ makedir := \$(dir \$(call lastword,\$(MAKEFILE_LIST)))

 MAKEARGS := -C $1
 MAKEARGS += O=\$(if \$(patsubst /%,,\$(makedir)),\$(CURDIR)/)\$(patsubst 
%/,%,\$(makedir))
+MAKEARGS += BR2_EXTERNAL=\$(realpath \$(BR2_EXTERNAL))

 MAKEFLAGS += --no-print-directory

Again this is only a suggestion but otherwise I'll ack the patchset.

Thanks,
-Ryan
