Move platform-specific README files to doc/platforms

Issue #515 (bdwgc).

Make doc folder less overwhelming by moving platform specific docs to
their own folder.

* Makefile.am (dist_doc_DATA): Change doc/README.* to
doc/platforms/README.* for README.DGUX386, README.Mac, README.OS2,
README.aix, README.amiga, README.arm.cross, README.darwin,
README.emscripten, README.ews4800, README.hp, README.linux, README.sgi,
README.solaris2, README.symbian, README.uts, README.win32,
README.win64.
* README.md (General Description, Installation and Portability): Update
links to README.win32, README.win64 and README.* files.
* doc/debugging.md (Bus Errors and Segmentation Violations): Put
README.win32 in quotes (to match that in other .md files).
* doc/README.DGUX386: Move to doc/platforms folder.
* doc/README.Mac: Likewise.
* doc/README.OS2: Likewise.
* doc/README.aix: Likewise.
* doc/README.amiga: Likewise.
* doc/README.arm.cross: Likewise.
* doc/README.darwin: Likewise.
* doc/README.emscripten: Likewise.
* doc/README.ews4800: Likewise.
* doc/README.hp: Likewise.
* doc/README.linux: Likewise.
* doc/README.sgi: Likewise.
* doc/README.solaris2: Likewise.
* doc/README.symbian: Likewise.
* doc/README.uts: Likewise.
* doc/README.win32: Likewise.
* doc/README.win64: Likewise.
* doc/simple_example.md (Other platforms): Replace doc/README.xxx to
doc/platforms folder.
