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.
This might be specific to gcc or Linux
as I didn't see it with clang + macOS.

wget is missing from some system (like macOS and Windows native),
it's better to use curl to simplify build environment.
