Thanks for update.

+  -Wl,--whole-archive
+  -Wl,${LLVM_LIBGCC_SYSROOT}/lib${LLVMLIB_DIR_SUFFIX}/${LLVM_LIBGCC_UNWIND_STATIC}
+  -Wl,${LLVM_LIBGCC_SYSROOT}/lib${LLVMLIB_DIR_SUFFIX}/${LLVM_LIBGCC_COMPILER_RT}
+  -Wl,--version-script,${LLVM_LIBGCC_GCC_S_VER}
----------------
These two libs could be added as dependency too as gcc_s_ver.

+    defined(__ARM_ARCH_7A__) && defined(__ARM_EABI__) && \
+    defined(__ARM_FP) && __ARM_FP == 0xC
+  #define LLVM_LIBGCC_ARM_GNUEABIHF
----------------
that should work as 
__ARM_FP means HW floating point is available as
	• Bit 1 - half precision (16-bit).
	• Bit 2 - single precision (32-bit).
	• Bit 3 - double precision (64-bit).
or
	• 0x04 for single-support.
	• 0x0C for single- and double-support.
	• 0x0E for half-, single-, and double-support.
