Upstream clang3.6 still doesn't allow change of calling convension of
__builtin_isnan from the default to "softfp" (via __attribute__((pcs("aapcs"))))
as required by bionic libm.so for 32-bit ARM. Let's hope clang3.7
fix that. See upstream bug http://llvm.org/bugs/show_bug.cgi?id=20958

Fixes two issues:
1. Remove redundant check for hard-float in Teapot/MoreTeapots and ndk_helper
they depend. The ndk-build system add those flags already for armeabi-v7a-hard
2. native-audio in debug build: assert on the non-existance var

It appears that upstream 3.5 still can't accept __builtin_isnan redeclared
with calling convention, eg.
cat > isnan.c <<EOF
int __builtin_isnan(double) __attribute__((pcs("aapcs")));
EOF
clang -target armv5te-none-linux-androideabi -c isnan.c
isnan.c:1:5: error: function declared 'aapcs' here was previously declared without calling convention
int __builtin_isnan(double) __attribute__((pcs("aapcs")));
^
isnan.c:1:5: note: previous declaration is here

Also
1) rename lib -> lib64
2) add src/ for android-20/arch-arm64 and arch-mips64
3) delete android-9/arch-arm64 and arch-mips64

* Add i386/elf_machdep.h, it is used during the build of 32-bit part of
multilib compiler;
* Remove page.h. See https://android-review.googlesource.com/#/c/83299;
* Update other x86 headers from bionic for compatibility which are
required for successful build;

* Cleaned up obsolete link in android-9
* Add symlink to lib-bootstrap in android-9
* Add symlink to crt* files sources so that we can build crt*.o for x86_64
* Moved static libs from lib to lib64 so that they can coexist with 32-bit libs
and automatically picked up by multilib compiler. Just plain move, nothing
changes;

Similar to clang 3.3, it seems that clang 3.4 declares an incompatible
function prototypes for __builtin_isnan(). To workaround this issue,
we should not declare the function prototype for __builtin_isnan().
Note: Though it may be good to fix this in clang type checker, like
__builtin_nexttoward(), however it seems non-trivial since __builtin_isnsn()
might be overloaded. We can revert this after we have fixed the
clang builtin definition.

wait4() was incorrectly declared in <sys/wait.h>, but only added to the
C library in Android 4.3 (API level 18) [1]
This patch:
- Removes the wait4() declarations for any <sys/wait.h> header before
API level 19.
- Brings the API level 19 <sys/wait.h> which correctly declares wait4().
- Update the libc.so.functions.txt for API level 19 of all platforms
to include the exported symbol.
NOTE: This does not bring the static libc.a to API level 19, which means
it is stuck at API level 9 for ARM.
See [2] for the corresponding NDK tests.

Annotate __builtin math functions with __NDK_FPABI_MATH__ too.
1. __attribute__((pcs("aapcs"))) has no effect on codegen when __buitlin
function is emitted inlined.
2. When __builtin call into regular function in Android's libm, it has
proper attribute which observes soft float-abi

The mkdtemp() function has always been implemented in the C library
(see [1] for proof) but was missing a declaration in <stdlib.h>, until
Android 4.0.1 [2]
This patch simply adds the missing declaration to former <stdlib.h>
versions. This makes it easier to build certain open-source programs
for Android, because auto-tools probing typically looks at the symbols
in libc.so to define HAVE_MKDTEMP, then the source fails to compile
because of the lack of declaration.
Note that the mkdtemp is also already listed in
platforms/android-*/arch-*/symbols/libc.so.functions.txt, which were
generated by parsing actual system libraries, and thus don't need to
be updated here.

Allow user code to be compiled with "-mhard-float" for armeabi-v7a
(which implies -mfloat-abi=hard), and either link with
1. Android native APIs which use softfp, or
2. A customized libm_hard.a which is compiled with -mhard-float. Need
-D_NDK_MATH_NO_SOFTFP=1

1. Add sincos, sincosf, and sincosl to API >= 9 (for ARM only,
because X86 and MIPS have it already)
2. Add nan, nanf, nanl, and tgammaf to API >= 13 (11 actually,
but we don't want to add another API which is not released)
3. Add log2, log2f, log2l, logbl, nexttoward, and nexttowardl to
API >= 18
