mkmf.rb: fix werror option

Browse source 
* lib/mkmf.rb (try_compile): pass the given werror flag to try_do
  to check if stderr is empty.
* lib/mkmf.rb (try_cflags, try_ldflags): default werror to true.
* win32/Makefile.sub (WERRORFLAG): remove useless option.  VC does
  not make warnings of unknown command option an error.
