m32r: add __ucmpdi2 to fix build failure
We are having build failure with m32r and the error message being:
ERROR: "__ucmpdi2" [lib/842/842_decompress.ko] undefined!
ERROR: "__ucmpdi2" [fs/btrfs/btrfs.ko] undefined!
ERROR: "__ucmpdi2" [drivers/scsi/sd_mod.ko] undefined!
ERROR: "__ucmpdi2" [drivers/media/i2c/adv7842.ko] undefined!
ERROR: "__ucmpdi2" [drivers/md/bcache/bcache.ko] undefined!
ERROR: "__ucmpdi2" [drivers/iio/imu/inv_mpu6050/inv-mpu6050.ko] undefined!
__ucmpdi2 is introduced to m32r architecture taking example from other
architectures like h8300, microblaze, mips.
