So what's going on here? The gcc command line includes
-I../../grub-core/gnulib, which is correct given your build tree layout,
and there's no -iquote or -I- funniness going on. The build log shows
that alloca.h was created earlier. Could you check whether this file
still exists after that failure?
/home/keshav_pr/Desktop/New/Source/grub2_BZR/GRUB2_EFI_BUILD_DIR_x86_64/grub-core/gnulib/alloca.h
Failing that, try repeating that gcc command in the stated directory
under strace, and see where it's looking for alloca.h.
