No appends/prepends or custom functions in the recipe. This recipe is for a lovely Broadcom driver/userspace glob and I'm trying to troubleshoot it with x64 but not being able to get a correct working env makes life hard. Any idea's of where I might be going wrong?

Check that Makefiles are not overriding CC/CXX/LD etc. some old crufty
Makefiles I have seen doing that, you might see something like

CC = ${CROSS_COMPILE}gcc etc. which you should convert to weak defines
e.g. CC ?= ....
