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.
