"Run tests with low max_cmd_len" on MSYS/MSVC

[Peter Rosin]

Hi!

This patch together with [1] and [2] will make "Run tests with
low max_cmd_len" on MSYS/MSVC behave the same as the individual
tests.

The patch fixes a couple more of the /abs/path issues already
fixed in [1] and [2]. However, I fear that these hunks may be
more controversial, as they touch code that affects other
platforms as well.

Cheers,
Peter

        Convert paths to host format
        * libltdl/config/ltmain.m4sh (func_mode_link): When exporting
        symbols, linking and creating archives using command files (or
        response files), make sure that both the name of the command
        file and the content are made up of file names in a format
        appropriate for the host. Fixes stresstest.at on MSYS/MSVC when
        run with low command line length.
