Hi

drivers/ide/Makefile seems broken on 2.4.21-rc1 (it was OK on 2.4.20,
and not on 2.4.21-pre6 and 2.4.21-pre7).

I try to build a kernel with Old hard disk (MFM/RLL/IDE) support only 
(and without Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support).

Here is my .config:

#
# ATA/IDE/MFM/RLL support
#
CONFIG_IDE=y

#
# IDE, ATA and ATAPI Block devices
#
# CONFIG_BLK_DEV_IDE is not set
CONFIG_BLK_DEV_HD_ONLY=y
CONFIG_BLK_DEV_HD=y
CONFIG_IDEDMA_AUTO=y
# CONFIG_IDEDMA_IVB is not set
# CONFIG_DMA_NONPCI is not set
CONFIG_BLK_DEV_PDC202XX=y
CONFIG_BLK_DEV_IDE_MODES=y
# CONFIG_BLK_DEV_ATARAID is not set
# CONFIG_BLK_DEV_ATARAID_PDC is not set
# CONFIG_BLK_DEV_ATARAID_HPT is not set
# CONFIG_BLK_DEV_ATARAID_SII is not set

The resulting kernel has no support for ide hard disks:

# ls -l drivers/ide/*.o
-rw-r--r--    1 root     root            8 apr 23 08:56 drivers/ide/idedriver.o
#

The following patch fixes the problem for the x86 arch (sorry, I have no
access to other archs).

The kernel was built on a x86 computer running a debian woody (gcc
2.95.4 and glibc 2.2.5).
