anvl: Remove the omap34usbboot/out directory
anvl: Add precompiled omap34usbboot binaries for i386 and x86_64

The i386 binaries were compiled with -m32 flag added to the
src/omap34usbboot/Makefile HOST_CFLAGS.

anvl: Pass the omap dieid to the install script

This can then be used by the install script on host PC to
talk to the right device.

anvl: Added a minimal gitignore file
anvl: Update install script to detect between x86_64 and i368

Use the locally compiled binary if it exists, otherwise try to
use the precompiled binaries. Also use getopt for the arguments:

usage: ./omap-usb-install [-u | --update] [-irootfs.tar.gz | --install=rootfs.tar.gz]

Note that the rootfs.tar.gz is not yet being used.
