Well I finally figured out why building on Ubuntu fails. It default
shell is dash, and 'source' is a bash builtin command. The portable
equivalent is '.' (dot).

The fix is:

-- >8 --
-toolchain = $(shell source ./edk2-funcs.sh && qemu_edk2_get_toolchain $(1))
+toolchain = $(shell . ./edk2-funcs.sh && qemu_edk2_get_toolchain $(1))

I was wrong, it is sourced. See self-reply at top of this post.
