Pirama Arumuga Nainar 80ba345f0e Change STL for Windows to libc++.
- Link libgcc_eh, which needs pthread, which in turn depends on
kernel32.  Wrap the libraries with --start-group and --end-group and
remove duplicates.
- Use SjLj exceptions for 32-bit.  libgcc_eh implements SjLj exception
model for 32-bit.
- Disable visibility annotations for libcxx and libcxxabi since we are
only going to support these as static libraries.
- Use Win32 threads.  MinGW pthreads throws an error when building
libcxx since it's pthread_mutex_initializer is not constant (needs a
cast).

Test: Build and test Windows binaries under Wine.

Dan Albert 9262b6fead Disable availability macros in libc++ on Darwin.
libc++'s headers are annotated with availability macros that indicate
which version of Mac OS was the first to ship with a libc++ feature
available in its *system's* libc++.dylib. We do not use the system's
library, but rather ship our own. As such, these availability
attributes are meaningless for us but cause build breaks when we try
to use code that would not be available in the system's dylib.

Test: removed the darwin check and checked showcommands on linux

Dan Willemsen a3a06feeed Add -lm to the default libs for Linux & Darwin
libm is a default library for device builds, so default it for host
builds as well.

Also removes duplicate additions of -ldl, -lpthread, -lm and -lrt.

Dimitry Ivanov cdf3927ec4 Add libdl.so to the list of system shared libs
Note that libdl is already (always) implicitly loaded
because libc.so has a dependency on it.

Also make sure that libc.so always preceding libdl.so
in dt_needed list.

Dan Willemsen c9aa6fca41 Fix building static linux binaries
BUILD_HOST_static has been broken because I was stripping
-Wl,--start-group/-Wl,--end-group into a separate set of ldflags instead
of keeping them wrapped around some of the ldlibs. So don't pass some of
the build system flags through the ldlibs checker.

Dan Willemsen 441d646c6f Fix C++ on Darwin
We've been including the system libc++ headers even if we're building
against our version of libc++. Stop doing that, and only add the headers
to our path if we're using the system libraries.

If nothing is specified, on recent OSX versions, libc++ is the default
c++ library instead of libstdc++. We've been explicitly including the
libc++ headers on all versions, but that breaks old versions. Force us
over to libc++, since the system libstdc++ does not support C++11, and
libc++ is still supported on our oldest version (10.8).

Dan Albert dc30a16ba2 Hide unwinder symbols in each binary.
These symbols need to always be resolved for each binary. Making these
symbols hidden means that we will get a build breakage if this doesn't
happen, and should also prevent the situation where one unwinder's
symbols are visible to the other.

Dan Albert 5036729c41 Add unwinder linking to STL setup.
Previously we were bundling this into libc++ and having each binary
resolve its symbols from there. This means that the unwinder that gets
used for a given binary is sensitive to the order in which its
libraries are linked. Making this a static library dependency of each
binary means the right unwinder will always be used.

Dan Albert 4f2afde252 (Hopefully) fix the Mac build.
The Mac linker doesn't understand --start-group, which is needed for
properly linking libgcc/libc statically. It isn't needed for dynamic
executables though, so use that driver behavior where appropriate.

Dan Albert 8bf4cc97c2 Fix building static host executables.
BUILD_HOST_static=1 forces all host binaries to be statically linked.
Since -nodefaultlibs was passed (to disable libstdc++), libgcc wasn't
being passed. This change emulates the driver's behavior.

Also fix default STL selection for BUILD_HOST_static.

Dan Albert 93766b28ce Make libc++ the default STL.
Previously, code defaulted to using libstdc++ (which was GNU libstdc++
on the host, or Bionic's "libstdc++" on the target). Now we default to
libc++. The exception for this is when using mingw, because we cannot
build libc++ for mingw.

It is libstdc++.so, after all, and the naming makes sense for the host

Because LOCAL_CXX_STL modifies a module's required shared libaries,
