This commit brings a number of improvements to the grub packaging: * It builds grub with the host compiler, which is needed so that we can build a 32 bits grub even if the target architecture is x86-64. To make sure we have a host compiler capable of generating 32 bits code, grub now selects the BR2_HOSTARCH_NEEDS_IA32_COMPILER option. Building with the host compiler is done by cheating and passing $(HOST_CONFIGURE_OPTS) in GRUB_CONF_ENV. * Some additional CFLAGS are added to make sure grub builds properly with modern compilers (-O0, --build-id=none, -fno-stack-protector). * Removal of the GRUB_INSTALL_STAGING_CMDS which were not used, since GRUB_INSTALL_STAGING was not set to YES. * Installation of the "grub" binary in $(HOST_DIR) instead of $(TARGET_DIR) since it's actually used only on the host to install grub into an image or device. * Removal of the grub uninstall commands, since they are generally considered useless.
