Subject: [boost] [predef] The predef-check functionality is not working on the Android regression tests

I do not believe that predef-check is working at all on the Android
regression tests. Predef itself appears to be working as far as the
predef macro values. But attempting to use predef-check to set a
<cxxflags> value is just not happening. I can attest that just setting a
<cxxflags> value, outside of using predef-check, does work correctly on
the Android regression tests.

The failure is occurring on my VMD tests. But you can also see the
failure on the predef tests also. Looking at the info_as_cpp test output
you can see that BOOST_COMP_CLANG > 0 and BOOST_OS_LINUX = 0. Yet if you
look at the corresponding check_value test at
you will see that the output is 'CHECK_VALUE == undefined', whereas if
predef-check were actually working the output should be 'CHECK_VALUE ==
1' ( or 'true' ).

In all other environments predef-check is working. Maybe this failure of
predef-check somehow occurs because the Android tests are a
cross-compile, being done on a Unix system but targeting the Android.
But for whatever reason the inability of getting predef-check to work
keeps my VMD tests from adding the '-std=c++0x' option and the VMD tests
all fail without that option since the variadic macro support in VMD for
gcc needs C++11 support or better.
