"Link option thorough search test" on MSYS/MSVC

[Peter Rosin]

Hi!

This patch together with [1] will make the "Link option thorough
search test" pass on MSYS/MSVC using the pr-msvc-support branch.
This patch makes manifest embedding and cl command files work
when facing POSIX /absolute/path/names that MSYS fails to convert
to win32 paths due to prefixes of the arguments (prefixes in
these cases are -outputresource: and @).

Cheers,
Peter

        Convert POSIX paths with prefixes to host format for MSYS/MSVC
        * libltdl/m4/libtool.m4 (_LT_LINKER_SHLIBS, _LT_LANG_CXX_CONFIG)
        [mingw] <cl>: Make sure the -outputresource: path for the
        manifest tool is in Win32 format. Same for the MSVC command file
        containing the exports.
