 Support version specifiers in platforms option

 To use this functionality, add one or more elements to platforms of the
 form: platform operator version [operator version] ...

 Elements that do not have all three of these components are ignored, so
 existing usage like 'platforms darwin' continues to be displayed but
 doesn't do anything else.

 Each element where the platform matches the current os.platform is
 processed by applying each operator to compare os.version with the
 corresponding version. Operators supported are ==, !=, >, <, >= and <=.
 For == and !=, a string comparison that allows globs is used. For the
 rest, vercmp is used.

 If any of the comparisons evaluates to false, the default value of
 known_fail is set to yes.

 Usage example: A port that works on Darwin versions between 16 and 22
 inclusive, except for 18.2.x, and doesn't work on Linux:
 platforms   {darwin >= 16 != 18.2.* < 23} {linux != *}

 The special value 'any' can also be used to indicate broad
 compatibility of binary archives (not of the port itself). This only
 has an effect on the archive name, allowing the same archive to be used
 on either all platforms or all versions of one or more platforms.
 Example, the same archive will work anywhere:
 platforms   any

 An archive built on darwin will work on any darwin version, but not
 on other platforms:
 platforms   {darwin any}

 This can be combined with version specifiers if needed:
 platforms   {freebsd any} {darwin > 15}
