Re: [PATCH v2 1/1] Makefile: pass -ansi option to cmd_gen_envp

Without the '-ansi' option, the 'linux' string in env. files is replaced with the string '1 '. For example, in the board/armadeus/opos6uldev/opos6uldev.env file,

kernelimg=opos6ul-linux.bin

becomes

kernelimg=opos6ul-1 .bin

in the include/generated/env.in file.

That's because 'linux' is a System-specific Predefined Macros. [1]

Pass the '-ansi' option as suggested by the GCC documentation. [1]

So when the .dtb files are built, we use

-x assembler-with-cpp -undef

and that -undef seems to suppress a lot more than just the linux and unix defines. So I wonder if this case should also use that? I think that would also allow the c++ comments to remain.
