According to the C++ standard, std::unexpected() can throw the
exception.  Thus, we should not specify the exception specifier (i.e.
noexcept) and we should not capture the exception thrown by the
user-specified unexpected handler.

It seems that linux/stddef.h no longer defines NULL, and
crtbegin.o can not be compiled after the adoption of uapi.

This commit fix this issue by removing unnecessary isystem
and nostdinc option.  Now, the compilation command in
gen-platforms.sh should be similar to the build rules for
crtbegin.o in the bionic Android.mk.

According to C++ standard, the default destructor will be
deleted if one of the destructor of the base classes is
inaccessible.  In our cases, the private inheritance will
make the destructor inaccessible to the derived class.
In this commit, we are going to change the "private"
inheritance to "protected" inheritance so that this test
case can be standard compliant.

This commit is cherry-picked from libc++abi upstream
r187429, which is written by Howard Hinnant.  The original

    tip-of-trunk clang has corrected some access checks for
    special members in a virtual inheritance hierarchy.
    Change a few private inheritances to protected.  This
    change will not impact what the test was testing.  This
    fixes PR16753.

Set SHELL as env. var. instead of passing it to python.exe which
can't understand it.

wait4() is only available since API level 19, before that the
C library didn't export the symbol. See [1] for the
corresponding NDK platforms patch.

+ Rewrite the test to avoid sleeping and too much copy-and-paste.

+ Add a test-wait-api19 test that links the test program against
  API level 19 system libraries, which include wait4().

This adds a musl-based printf() implementation to the Android support
library. This adds support for exotic formatters like %a (hexadecimal
floats), required by the libc++ unit test suite, as found by Nico
Weber (thakis@chromium.org)

+ Add missing implementation of frexp()/frexpf()/frexpl()
  (required by vfprintf.c)

+ Minimize the differences between our vfwprintf.c implementation
  and the original musl one, by moving the output wrapper structure
  to src/stdio/stdio_impl.[hc].

Note: std::terminate() and std::unexpected() are 'nothrow' in C++11,
      but they are _not _ 'throw()' in C++98, so introduce a new
      _GABIXX config macro to deal with this.
