I've attached mine and Kishore's. Mine builds grub, while his does not.

I noticed that Kishore's config.log differs from mine in some configure tests. For example:

Mine contains (config.log-dvhart):

While there is no reference to stubs.h in Kishore's config.log (confi-1.log):

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.

I also found that Kishore's config.log includes:
freetype_cflags='-I/usr/include/freetype2'
freetype_libs='-lfreetype -lz'

While mine includes:
freetype_cflags='-I/build/poky/sugarbay/tmp/sysroots/sugarbay/usr/include/freetype2 -I/build/poky/sugarbay/tmp/sysroots/sugarbay/usr/include'
freetype_libs='-L/build/poky/sugarbay/tmp/sysroots/sugarbay/usr/lib -lfreetype'

This would certainly be cause for a QA test failure.
Yes, this is certainly the problem.

Perhaps a DEPENDS=freetype in the grub recipe is in order?

Alternatively, we could see about configuring it without freetype.
I'd tend to favour the latter unless someone can convince me freetype
support adds something really useful to grub.
