Update NDK compatlib for 4.1.2.

The replacement new failures present in newer versions are present
here as well, with the following new issues:

XPASS std/localization/locale.categories/category.numeric/locale.nm.put/facet.num.put.members/put_long_double.pass.cpp

This is from the -NaN formatting fix in bionic. We previously had this
wrong, and the upstream test is also wrong. There's currently an XFAIL
for Android in this test because I haven't fixed the upstream test
yet. After that is done, I'll need to teach the test runner how to
XFAIL older Android versions...

FAIL std/localization/locale.categories/category.ctype/facet.ctype.special/facet.ctype.char.dtor/dtor.pass.cpp
    dtor.pass.cpp:39: int main(): assertion "globalMemCounter.checkDeleteArrayCalledEq(1)" failed

Haven't investigated this one yet. http://b/19412688

Note that this also needs the libgcc link ordering to be fixed in the
build system, as we'll otherwise depend on libgcc symbols from libc
that may or may not have been there.

The build fix can't be submitted because the proper link order causes
the libgcc unwinder to be used instead of the EHABI one:
