I have only
MACHINE_FEATURES += "efi"
KERNEL_FEATURES_append_cedartrail += "cfg/efi-ext.scc".
I am not having IMAGE_FSTYPES += "live".
Thanks
Kishore.

More accurately:
MACHINE_FEATURES_append_qemux86=" efi pcbios"
KERNEL_FEATURES_append_qemux86=" cfg/efi-ext.scc"
IMAGE_FSTYPES += "live"
With these added to local.conf and building for qemux86 I see the same
configure failures reported by Kishore and Josef:
| ../../lib/autoconf/lang.m4:194: AC_LANG_CONFTEST is expanded from...
| acinclude.m4:363: grub_CHECK_STACK_ARG_PROBE is expanded from...
I've discussed in IRC with Nitin and he thinks this may be related to
the automake update and is looking into it.
