* --regen
Re-generate build.ninja only when necessary. If either
1. .mk file is updated,
2. environment variable is updated,
3. $(wildcard) result is changed, or
4. $(shell) result is changed,
ckati will regenerate ninja file. This check takes only ~1
second, so incremental build will become much faster even
without "fastincremental" target.
* --ignore_dirty=out/%:
Some .mk files in out/ (e.g.,
out/target/product/generic/previous_build_config.mk)
are updated while ckati is running. With this flag, ckati
does not regenerate build.ninja when they look modified.
This should be OK for ninja based build, as ninja handles
command line changes nicely.

The build system removes targets like "PRODUCT-full-eng" from
MAKECMDGOALS in build/core/product_config.mk.
Without this change, such target isn't passed to kati.

If USE_NINJA=true, use kati to translate makefiles into ninja files,
and then execute them with ninja.
Builds kati from source using simplified versions of the rules
in binary.mk and definitions.mk.
Adds two new goals when USE_NINJA=true: generateonly will regenerate
build.ninja but not rebuild (useful for comparing build.ninja output
between runs), and fastincremental will skip regenerating build.ninja
and go directly to running ninja, providing ~5 second incremental
builds.
