[oe-users] Update on gumstix build

[Steve Sakoman]

I tried the latest checkins for gumstix this evening.

Config details:   gumstix.conf for machine, distro was
angstrom-2007.1(uclibc),  which results in building
linux-2.6.21 using linux.inc.

I used angstrom-minimal-image as the target.

The build did not complete due to an error in do_rootfs when populating /dev
with the info from org.openembedded.dev/files/device_table-minimal.txt.  It
fails because there are a few non /dev entries in the table (/bin/tinylogin,
/bin/mount, and /bin/unmount).  Because only /dev exists at this point in
the build process, the creation of the /bin entries fails.

To get the build to proceed further, I removed the 3 /bin entries from that
table and restarted the build with a nuked tmp.

The build of angstrom_minimal_image now completed without error.
Unfortunately it still does not populate the /lib/modules directory in the
rootfs.  It does, however, now deposit a copy of
modules-2.6.21gum-r5-gumstix.tgz in build/tmp/deploy/uclibc/images/gumstix.

I also noticed that /bin/uImage has grown 2X from about 900KB to 1.8MB.

The jffs2 image previously would proceed through quite a bit of the boot
process before succumbing to the lack of /lib/modules.  The new image
doesn't do much at all:

Instruction Cache is ON
### JFFS2 loading 'boot/uImage' to 0xa2000000
Scanning JFFS2 FS: ........ done.
### JFFS2 load complete: 1930840 bytes loaded to 0xa2000000
## Booting image at a2000000 ...
Bad Magic Number
