  [GH #888] Add a cyg-desparse post-linker step

The cygwin linker up until 1.17.18 creates all its exes and shared libs
as sparse files, which reduces startup time of executables by a large percentage
(8-10x slower) because the code cannot be mmap'ed and not cached, it must be read
byte by byte. Again and again.

See http://cygwin.com/ml/cygwin-developers/2012-12/msg00011.html
