u-boot: Add specifying make options as part the config looping

There is a need to generate alternative versions of the uboot files
using the existing config looping system, but we need to add additional
settings to the make call rather simply specifying a different config.
Specifically we have two use cases:

1) We want to sign the same uboot files with two different keys where
   the key will be passed on the make call.
2) We want to include the alternative defconfigs from a different
   repository and need to add the path to this new location on the make
   command line.

This introduces a fourth value for the UBOOT_CONFIG settings:

  config,images,binary,make_opts

The values are placed into a new generated variable
UBOOT_CONFIG_MAKE_OPTS which is a '?' separated list since space can be
present if you need to specify multiple options.  This is handled by
changing IFS in the shell code when looping over the variable.

Additionally, add in a new variable UBOOT_MAKE_OPTS which is added to
the make calls in the various do_compile functions that do the actual
compiling.
