lld does not build in toolchain builder with USE="llvm-next default-libcxx"

Project Member Reported by manojgupta@chromium.org, Jan 12 2018 
lld links with llvm libraries. Therefore, it needs to use the same c++ library as llvm when building.
However, in toolchain builders llvm is built with libstdc++ but lld is getting built with libc++.
This creates an issue where lld can not be linked with llvm libraries.

This is a temporary issue which should go away once everything is migrated to libc++. Fix a fix to handle this for time being.

lld: Detect the c++ library used in llvm.

This is hack just to ensure that we can build
lld when llvm is linked with either of libc++ or libstdc++.

Remove this hack when everything is moved to libc++.

BUG= chromium:724628 

TEST=sudo emerge lld works when clang uses libc++ as default.
