fix race condition when using hardlinks to deliver into solver

We need to use "touch --no-dereference" on the delivered files.
Otherwise, it creates empty target file when you touch symlinks and
delivering the real target file might fail.

This caused many build failures when delivering:

    liblcms2.so -> liblcms2.so.2.0.4
    liblcms2.so.2 -> liblcms2.so.2.0.4
    liblcms2.so.2.0.4
