Subject: [PATCH] libs/libxx/libcxx.defs: Fix build error on Windows platform

The libcxx-X.Y.Z.src.tar.xz contains a symbolic link to a directory
that not exist as below.

`libcxx-X.Y.Z.src/test/std/pstl -> ../../../pstl/test/std`

Linux and macOS environment have no problem, but it causes an error
when extracting tarball on Windows platform. This symbolic link is not
actually used, so exclude it from extracting the tarball.
