[llvm-dev] LLVM-3.8.0 libcxx in-tree build fails with cmath error ::signbit has not been declared

Greetings!

I have been building llvm-3.6.x, 3.7.1 and 3.7.2 with (glibc-2.12.1,
binutils-2.24, gcc-4.9.2) almost same set if CMake flags.
However while building LLVM-3.8.0 using same CMake flags I am observing
projects/libcxx/include/cmath errors...
	...'::signbit' has not been declared
	...'::fpclassify' has not been declared
	...'::isfinite' has not been declared
	...

My environment is...
	Glibc-2.12.1
	Binutils-2.24
	Gcc-4.92.
	Llvm-3.8.0

Cmake flags...
        -DBUILD_SHARED_LIBS=ON \
        -DCMAKE_BUILD_TYPE="Release" \
        -DCMAKE_CXX_COMPILER=$GCC_ROOT/bin/g++ \

        -DLLVM_PARALLEL_LINK_JOBS=15 \
        -DLLVM_TARGETS_TO_BUILD="X86" \
        -DLLVM_TARGETS_WITH_JIT="X86"

Any suggestions?

Thank you in advance.
