$ emake -j2 O=../build/omap4/ uImage V=2
...
  CHK     include/generated/compile.h
echo '  Kernel: arch/arm/boot/Image is ready'
  Kernel: arch/arm/boot/Image is ready
  LZMA    arch/arm/boot/compressed/piggy.lzma - due to command line change
  AS      arch/arm/boot/compressed/piggy.lzma.o - due to: arch/arm/boot/compressed/piggy.lzma
  LD      arch/arm/boot/compressed/vmlinux - due to: arch/arm/boot/compressed/piggy.lzma.o
  OBJCOPY arch/arm/boot/zImage - due to: arch/arm/boot/compressed/vmlinux
echo '  Kernel: arch/arm/boot/zImage is ready'
  Kernel: arch/arm/boot/zImage is ready
  UIMAGE  arch/arm/boot/uImage - due to: arch/arm/boot/zImage
Image Name:   Linux-3.7.0-rc3+
Created:      Sun Nov  4 13:31:13 2012
Image Type:   ARM Linux Kernel Image (uncompressed)
Data Size:    1756112 Bytes = 1714.95 kB = 1.67 MB
Load Address: 0x80008000
Entry Point:  0x80008000
echo '  Image arch/arm/boot/uImage is ready'
  Image arch/arm/boot/uImage is ready

This happens every time - Kbuild always thinks that the LZMA command has
changed.  Here's the .cmd file for this:

cmd_arch/arm/boot/compressed/piggy.lzma := (cat arch/arm/boot/compressed/../Image | lzma -9 && printf \\\\200\\\\111\\\\113\\\\000) > arch/arm/boot/compressed/piggy.lzma || (rm -f arch/arm/boot/compressed/piggy.lzma ; false)

I suspect it's those multiple \ which are causing problems...
