Dan Willemsen b011810c25 Optimize rebuilds by reducing $(shell) usage 
$(shell) isn't particularly fast in Kati, and they have to be executed
both when reading the makefiles and determining whether the ninja file
needs to be regenerated.

Right now, the regen time is mostly hidden because we run them in
parallel. We've also configured it to ignore any commands that contain
"echo", "date", or the output directory. That happens to remove most
commands that contain side effects, so running them in parallel is fine.

But the side effects contain some important things, like the clean up
necessary when switching products. So I'm removing those filters, and
then we'll need to run the shell commands in sequence, since there will
be side-effects. That makes regen take longer though, so use pure-Make
implementations instead of $(shell) where possible.

This set of changes reduces aosp/master aosp_arm64-eng build $(shell)
usage and time by 2/3:

*kati*: func shell time: 3.135095 / 709
*kati*: func shell time: 1.067331 / 236

Bug: 30947985
Test: Manual test lines for math functions
Test: Compare build-aosp_arm64.ninja before/after

## Common build system definitions. Mostly standard
## commands for building various types of targets, which
## are used by others to construct the final targets.
##
# These are variables we use to collect overall lists
# of things being processed.
# Full paths to all of the documentation
ALL_DOCS:=
# The short names of all of the targets in the system.
# For each element of ALL_MODULES, two other variables
# are defined:
# $(ALL_MODULES.$(target)).BUILT
# $(ALL_MODULES.$(target)).INSTALLED
# The BUILT variable contains LOCAL_BUILT_MODULE for that
# target, and the INSTALLED variable contains the LOCAL_INSTALLED_MODULE.
# Some targets may have multiple files listed in the BUILT and INSTALLED
# sub-variables.

# Full paths to targets that should be added to the "make droid"
# set of installed targets.

# The list of tags that have been defined by
# LOCAL_MODULE_TAGS. Each word in this variable maps
# to a corresponding ALL_MODULE_TAGS.<tagname> variable
# that contains all of the INSTALLED_MODULEs with that tag.
ALL_MODULE_TAGS:=
# Similar to ALL_MODULE_TAGS, but contains the short names
# of all targets for a particular tag. The top-level variable
# won't have the list of tags; ust ALL_MODULE_TAGS to get
# the list of all known tags. (This means that this variable
# will always be empty; it's just here as a placeholder for
# its sub-variables.)
ALL_MODULE_NAME_TAGS:=
# Full path to all files that are made by some tool
ALL_GENERATED_SOURCES:=
# Full path to all asm, C, C++, lex and yacc generated C files.
# These all have an order-only dependency on the copied headers
ALL_C_CPP_ETC_OBJECTS:=
# The list of dynamic binaries that haven't been stripped/compressed/etc.
ALL_ORIGINAL_DYNAMIC_BINARIES:=
# These files go into the SDK
ALL_SDK_FILES:=
# Files for dalvik. This is often build without building the rest of the OS.
INTERNAL_DALVIK_MODULES:=
# All findbugs xml files
ALL_FINDBUGS_FILES:=
# GPL module license files
ALL_GPL_MODULE_LICENSE_FILES:=
# Target and host installed module's dependencies on shared libraries.
