You are probably not exporting flags correctly to build the kernel. Did you look at everything the kernel.bbclass is changing (as in what linker flags it might be overriding?)

In fact just try:

$ LDFLAGS= make modules

devshell does not properly set every variable, that's what the recipe is for. I think this can be marked NOTABUG.

Comment 3 Saul Wold 2012-09-04 21:04:58 UTC 
You can also look at the temp/run.do_compile script to see what variable are set and the shell code overrides.

I agree probably not a bug.
