When USE_CLANG_PLATFORM_BUILD is not set, default will be clang/llvm.
USE_CLANG_PLATFORM_BUILD=false can be used to select gcc as default.

Running zipalign is no longer needed because signapk takes care of
alignment.

Without this if a Java libraryw with LOCAL_NO_STANDARD_LIBRARIES doesn't
have core-libart in its LOCAL_JAVA_LIBRARIES, it would use core-libart
as bootclasspath but without having dependency on it.

  enable -fstack-protector-strong

This results in nearly all functions with the possibility of stack
corruption getting stack canaries, because it applies to any function
taking a reference to the frame or with a local array rather than just
the functions with arrays larger than 8 bytes. It was developed for use
in Chrome (and Chrome OS) and has also been adopted by various other
distributions (Arch, Fedora, Ubuntu, etc).

The code size increase ranges from ~1.5% to ~2.5%, compared to ~0.3% to
~0.7% with the more conservative switch. The increase in the performance
loss is usually minimal. The overall size increase once everything other
than C and C++ code is taken into account is minimal, and it greatly
improves the mitigation of stack buffer overflow vulnerabilities.

  Gmake doesn't like newline in macro expansion result.

When $(call func) in the makefile text expansion includes newline, gmake
reports error "missing separator". But it's fine if the expansion includes
only spaces. That's a bit odd.
This change fixes the "missing separator".

  Sanity check LOCAL_SRC_FILES_EXCLUDE

This changes the build system to no longer run zipalign except for
those prebuilts which do not need to re-signed.

Running zipalign is no longer needed because signapk takes care of
alignment. For those prebuilts which do not need to be re-signed
signapk is not invoked and thus zipalign is still needed because the
prebuilts may not have been aligned properly. This exemption will go
away once prebuilts are properly aligned.

Error out if there is a file listed in LOCAL_SRC_FILES_EXCLUDE but not in
LOCAL_SRC_FILES. This should catch typos or other mistakes that would
otherwise be missed.
