[PATCH 4/5] grub-efi: Do not use help2man

[Darren Hart <dvhart@linux.intel.com>]

Fixes [YOCTO #2527]

Modify configure.ac and the generated configure script to avoid using
help2man during the compilation process. For grub-efi we are only
deploying the EFI payload and are not installing grub on the target
root filesystem. Therefor, we do not need the man pages.

Cleanup the SRC_URI whitespace while we add a line to it.

+Upstream-Status: Inappropriate (Bitbake build environment)
+
+We do not need the man pages when building just the EFI payload for the target,
+all the tools are built for the host. This does not trigger GRUB's built-in
+cross-compilation check, so force it. After the change to configure.ac,
+autogen.sh was run in devshell and the resulting configure was used to generate
+the configure diff. The configure diff was included to avoid having to add
+autogen.sh to a do_configure_prepend() routine which would slow down the build
+unnecessarily.
