Could someone comment on this?

gcc -DHAVE_CONFIG_H -I. -I..  -Wall -W  -DGRUB_MACHINE_PCBIOS=1
-DGRUB_MACHINE=I386_PC -m32 -nostdinc -isystem
/usr/lib/gcc/x86_64-linux-gnu/5/include

So we do have definitions from /usr/lib/gcc/x86_64-linux-gnu/5/include used.

How harmless/harmful is it?

We use it for va_args definition and related macros. I don't think we want
to reimplement those

Yeah, I'd say that that include directory is really part of the compiler
rather than part of the host system as such.
