./Makefile: export initial ramdisk compression config option
Make menuconfig allows one to choose compression format of an initial ramdisk image. But this choice does not result in duly compressed ramdisk image. Because - $ make install - does not pass on the selected compression choice to the dracut(8) tool, which creates the initramfs file. dracut(8) generates the image with the default compression, ie. gzip(1). This patch exports the selected compression option to a sub-shell environment, so that it could be used by dracut(8) tool to generate appropriately compressed initramfs images. There isn't a straightforward way to pass on options to dracut(8) via positional parameters. Because it is indirectly invoked at the end of a $ make install sequence. # make install -> arch/$arch/boot/Makefile -> arch/$arch/boot/install.sh -> /sbing/installkernel ... -> /sbin/new-kernel-pkg ... -> /sbin/dracut ...
