This is interesting. What its saying here is that your build system
compiler can't compile 32 bit (the -m32 flag) since there are no 32 bit
headers present. Kishore's must have 32 bit headers installed (or be a
32 bit system). We shouldn't be seeing those differences but what they
amount to I don't know without looking at grub in more detail.

Yes, this is certainly the problem.

I'd tend to favour the latter unless someone can convince me freetype
support adds something really useful to grub.
