Hack canonicalize_file_name (should be fixed in gnulib)

Needed when cross compiling.

The gnulib canonicalize_file_name override breaks finding cygwin1.dll.

When compiling natively, gnulib doesn't override
canonicalize_file_name, but gnulib has hardcoded defaults for cross
compiling, and the default is wrong for Cygwin.
