Move selection of C++ STL into the build system.
Preparing for migration from stlport to libc++. STL selection is done
with LOCAL_CXX_STL (valid values are default, none, libc++,
libc++_static, stlport, stlport_static, bionic).
The selection of the STL is as follows:
if LOCAL_CXX_STL == 'default'
ifdef LOCAL_SDK_VERSION
Use whatever STL the other NDK options have selected.
else
Use bionic's libstdc++ for target, GNU libstdc++ for host. This
is compatible with the existing build options.
endif
else
if LOCAL_CXX_STL == 'stlport'
Use stlport.
else if LOCAL_CXX_STL == 'libc++'
Use libc++.
else if LOCAL_CXX_STL == ''
Don't use any STL.
endif
endif
