[PATCH] D31638: [CMake][libcxx] Use check_c_compiler_flag to check for nodefaultlibs

[Petr Hosek via Phabricator via llvm-commits]

phosek added a comment.

The problem is that `check_cxx_compile_flags` adds the flag to `COMPILE_DEFINITIONS`when calling `try_compile` and that variable is only considered for compilation but not for linking where `-nodefaultlibs` actually makes a difference (I should probably add this into the description).
