It is only effective when compile with mips, although
development no longer has to check themselves

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.

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
See tests/device/hard-float/jni/Android.mk for details and restriction
on Clang

For some reason, the header was missing from previous NDK releases.
Note: the function symbols are properly listed in arch-$ARCH/symbols/libc.so.functions.txt
