I may be recipe configuration, however, here are my steps:

 >bitbake u-boot -c cleanall
 >bitbake u-boot -c fetch
 >bitbake -c devshell u-boot

in the new shell

 >make coreboot-x86 (without _config)

The output I got is as follows:

However this is the same out as when I do

 >make coreboot-x86_config
 >make all

This happens only when I'm trying to build inside the devshell, which 
lead me to believe that maybe the environment is not set completely,  
until at do_compile.
