linux-info explicitly looks at ${KV_DIR}/Makefile, whereas the presence of a GNUmakefile ought to override Makefile (eg, this is used to set ARCH=x86_64 on 32-bit userspace). In my case, I am using it to set CROSS_COMPILE since I need to build my kernel with a non-standard compiler, and linux-info is failing because it tries to execute various tests (part of Makefile) without the correct CROSS_COMPILE setting.
Can you give me the full steps to reproduce
1) Extract an x86_32 stage to make a chroot 2) emerge your favourite kernel sources and crossdev a x86_64-pc-linux-gnu toolchain 3) create /usr/src/linux/GNUmakefile containing: ARCH=x86_64 CROSS_COMPILE=x86_64-pc-linux-gnu- include Makefile 4) build kernel w/ `make && make modules_install` 5) Try to emerge anything using linux-info
