Paul Menzel 1a2494b7c7 Makefile: Allow to set file systems modules for default_payload.elf
By default all file system modules are added to the GRUB coreboot
payload `default_payload.elf`. This makes the image quite big,
especially as often not all modules are needed.

Introduce the variable `FS_PAYLOAD_MODULES`, which can be used to
explicitly set file systems modules to be added.

    $ make default_payload.elf
    test -f default_payload.elf && rm default_payload.elf || true
    pkgdatadir=. ./grub-mkstandalone --grub-mkimage=./grub-mkimage -O i386-coreboot -o default_payload.elf --modules='ahci pata ehci uhci ohci usb_keyboard usbms part_msdos ext2 fat at_keyboard part_gpt usbserial_usbdebug cbfs' --install-modules='ls linux search configfile normal cbtime cbls memrw iorw minicmd lsmmap lspci halt reboot hexdump pcidump regexp setpci lsacpi chain test serial multiboot cbmemc linux16 gzio echo help syslinuxcfg xnu affs afs bfs btrfs cbfs cpio cpio_be exfat ext2 f2fs fat hfs hfsplus iso9660 jfs minix minix2 minix2_be minix3 minix3_be minix_be newc nilfs2 ntfs odc procfs reiserfs romfs sfs squash4 tar udf ufs1 ufs1_be ufs2 xfs zfs password_pbkdf2 ' --fonts= --themes= --locales= -d grub-core/ /boot/grub/grub.cfg=./coreboot.cfg

    $ make default_payload.elf FS_PAYLOAD_MODULES="" # ext2 already in `--modules`
    test -f default_payload.elf && rm default_payload.elf || true
    pkgdatadir=. ./grub-mkstandalone --grub-mkimage=./grub-mkimage -O i386-coreboot -o default_payload.elf --modules='ahci pata ehci uhci ohci usb_keyboard usbms part_msdos ext2 fat at_keyboard part_gpt usbserial_usbdebug cbfs' --install-modules='ls linux search configfile normal cbtime cbls memrw iorw minicmd lsmmap lspci halt reboot hexdump pcidump regexp setpci lsacpi chain test serial multiboot cbmemc linux16 gzio echo help syslinuxcfg xnu  password_pbkdf2 ' --fonts= --themes= --locales= -d grub-core/ /boot/grub/grub.cfg=./coreboot.cfg
    $ ls -l default_payload.elf
    -rw-rw---- 1 joey joey 832976 Mar  7 12:13 default_payload.elf

So, the resulting payload size is around 370 kB smaller. (Adding it to
the CBFS, it will be compressed, so the effective size difference will
be smaller.)
