Support for building V8 with MinGW

V8 can now be build with MinGW. It still fails the following four tests in debug mode:

  mjsunit/parse-int-float
  mjsunit/mirror-array.js
  mjsunit/integer-to-string.js
  mjsunit/regress/regress-114.js

Building with MinGW has been tested with version 5.1.4 using GCC 3.4.5.

In addition to supporting MinGW this change also makes it more explicit which targets needs to link with which libraries.
