Details:

On Cygwin, when using CC=cl.exe (MSVC) as the compiler, some test cases fail
just because of unexpected carriage return output from test binaries.

Fortunately, with GNU diff there is the --strip-trailing-cr flag, which allows
to easily get the libtool test suite agnostic to CR, independent of any host
triplet used:

If 'diff --help' tells about the --strip-trailing-cr flag, attached patch does
wrap the host diff command to add that flag for when run as 'diff -u' via
$at_diff in the test suite, in addition to stop adding CR to expected output
files for mingw.

This allows to succeed following test cases when run on Cygwin with MSVC
environment and these configure options: CC=cl CXX="cl /TP" GCJ=no GOC=no
F77=no FC=no NM=no CFLAGS= CXXFLAGS=

  27: link against a preloaded static library
  30: deplibs_check_method
  40: build and link against a static library
  41: build and link against a dynamic library
  42: build both static and dynamic
  43: allow_undefined_flag
  49: static library interdependencies
 112: dlloader API

Thanks!
