[U-Boot] [PATCH v3 2/4] build/mkconfig: Add EXTRA_OPTS argument to make to modify build

[Matthew McClintock]

Allow users to pass in extra defines via make so they can
modify the build. Example

make P1022DS EXTRA_OPTS=NAND

is equivalent to

make P1022DS_NAND

v2: Fix tab indention, fix posix compliance
v3: Move appending $EXTRA_OPTS up higher before we set $TARGETS so we
    only need to append $EXTRA_OPTS to $options and not $TARGETS
