* fixed handling of paths/files with spaces in their name in link.res

on platforms where the `cat link.res` trick is used. Those must
    /not/ be quoted, because otherwise the shell assumes those quotes
    are part of the filename, and will escape the quotes themselves.

    Instead, write everything out without quotes, but set IFS to
    <newline> before doing the cat, so that only a new line is seen
    as a separator between items. The shell will then insert the
    necessary quotes to escape the spaces. One disadvantage: this
    means that other options, such as e.g. "-arch ppc" under Darwin,
    must now be written split over two lines to avoid the shell
    passing such parameters (which consist of two separate strings)
    as one single parameter (with an escaped space) to ld.
