  I agree that that would be a good idea.

  However, what if the patches are different for two configurations? They 
can be different because:

- there is a configuration option for custom patches, like 
BR2_LINUX_KERNEL_PATCH

- there are patches applied depending on configuration options, like 
BR2_LINUX_KERNEL_EXT_XENOMAI_ADEOS_PATCH

- there are manual modifications applied depending on some configuration 
option, like BZIP2_NOLARGEFILE_FIX_MAKEFILE

- override.mk appends to the FOO_PATCH variable

- BR2_EXTRA_PACKAGE_PATCH_DIRS (not committed yet, 
http://patchwork.ozlabs.org/patch/204216/ )

  So in practice, I'm afraid it's not feasible.

  Regards,
  Arnout
