  compile: support libfoo.a naming when wrapping Microsoft tools
  
  There is a future plan to provide some means to have Automake
  create static libraries that are named differently depending
  on the system [1].
  
  The background is that everyone has always named static libraries
  libfoo.a, except the Redmond crowd who names them foo.lib, and
  you have to jump through hoops to have Automake create libraries
  named foo.lib in the land of non-GNU Windows while still creating
  libfoo.a everywhere else.
  
  However, there is probably no sane way to accomplish that system
  dependent naming discussed in [1] without user intervention,
  which makes it necessary to support the classic libfoo.a naming
  when using Microsoft tools in the best possible way, for the
  benefit of all projects today and for future projects not
  opting in to whatever scheme is selected for the problem at
  hand.

  * lib/compile (func_cl_dashl): As a last resort, match -lfoo with
  libfoo.a, if that file exist on the library search path.
  * t/compile4.sh: Remove obsolescent workaround for the above.
  * t/compile6.sh: Extend to check that libbaz.a is indeed found
  when baz.lib and baz.dll.lib does not exist and that bar.lib
  and bar.dll.lib are preferred over libbar.a.
