extmk.rb: fix mingw make failure with make -jN

* common.mk (WPROGRAM): need same dependencies as PROGRAM.

* cygwin/GNUmakefile.in (uncommon.mk): move include position
  below WPROGRAM definition to be defined in uncommon.mk.

* ext/extmk.rb (all, static): fix make rubyw.exe failure with make -jN.
  If make of ruby.exe and rubyw.exe run in parallel, link dll and link
  exe run in parallel, which causes link failure on mingw. To fix this,
  we make ruby.exe and rubyw.exe in one make process.
  [ruby-core:48007] [Bug #7165]
