When the compilation of unpack200 was converted to the new build, some weird exceptions had to be made to make it come out exactly like the old build. It's different from all other executables by being linked with cl instead of link and with incremental option turned on. This causes the following two warning to be printed:

cl : Command line warning D9002 : ignoring unknown option '-pdb:c:/re/jdk8/4686/build/windows-amd64/jdk/objs/unpackexe/unpack200.pdb'
cl : Command line warning D9002 : ignoring unknown option '-map:c:/re/jdk8/4686/build/windows-amd64/jdk/objs/unpackexe/unpack200.map'

We should remove these exceptions and let unpack200 be compiled using the same patterns and procedures as other executables in the new build.
