Select target arch:
s   - sh       (Archos models)
m   - m68k     (iriver h1x0/h3x0, ifp7x0 and iaudio)
a   - arm      (ipods, iriver H10, Sansa, etc)
e   - arm-eabi (same as above, new testing toolchain)
i   - mips     (Jz4740 and ATJ-based players)
separate multiple targets with spaces
(Example: "s m a" will build sh, m86k and arm)

bunzip2: Compressed file ends unexpectedly;
	perhaps it is corrupted?  *Possible* reason follows.
bunzip2: Inappropriate ioctl for device
	Input file = (stdin), output file = (stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.
