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. -M 24817 3 sgw 2012-09-04 21:04:58 +0000 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.
