Relevant Makefile [1] lines: EXTRAVERSION = EXTRAVERSION := $(EXTRAVERSION)-omap1 I suspect it broke after in [2]. [1] http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap-2.6.git;a=blob;f=Makefile;hb=52a962f09ab2306a2ac6e22c2d3bac1a76ac8993 [2] http://sources.gentoo.org/viewcvs.py/gentoo-x86/eclass/linux-info.eclass?r1=1.60&r2=1.61
Also check 167385
The make-based check for EXTRAVERSION can fail as well. I'll see about using the make-based version and then falling back.
Should be fixed with linux-info.eclass rev 1.78 now.
