commit ffe8018c3424892c9590048fc36caa6c3e0c8a76 of the -mm tree
fixes the initramfs size calculation for e.g. s390 but breaks it
for 32bit architectures which do not define CONFIG_32BIT.
This patch fix the problem for PPC32 which will elsewise end up
with a __initramfs_size of 0.

Thanks for the hint!
In the future, please CC linux-arch, or at least lkml, for things like this,
as it broke allmost all 32-bit arches.
Only mips, s390, and score set CONFIG_32BIT for 32-bit builds.
Would have saved me a bisection on m68k...
I came up with the alternative patch below to fix it in a single place.

Subject: [PATCH] initramfs: Fix initramfs size for 32-bit arches
commit ffe8018c3424892c9590048fc36caa6c3e0c8a76 ("initramfs: fix initramfs size
calculation") broke 32-bit arches like (on ARAnyM):
VFS: Cannot open root device "hda1" or unknown-block(3,1)
Please append a correct "root=" boot option; here are the available partitions:
fe80 1059408 nfhd8 (driver?)

0302 137807 hda2 00000000-0000-0000-0000-000000000hda2
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,1)
As pointed out by Kerstin Jonsson <kerstin.jonsson@ericsson.com>, this is due
to CONFIG_32BIT not being defined.
Only mips, s390, and score set CONFIG_32BIT for 32-bit builds, so fix it for
all other 32-bit arches by inverting the logic and testing for CONFIG_64BIT,
which should be defined on all 64-bit arches.
