global: Update to 6.2.7

Also removed option "without-rebuilding-php-parser". Option no longer
needed as GNU Global is now distributed with the rebuild PHP parser by
default.

Closes Homebrew#16759.

-    GNU GLOBAL is distributed with a PHP parser generated with an
-    old version of flex(1). That parser has some limitation. See:
-      http://comments.gmane.org/gmane.comp.gnu.global.bugs/1439
-
-    Installing GNU GLOBAL with Homebrew will therefor rebuild the
-    PHP parser using Mac OS X' newer version of flex(1) which
-    generates a parser without the limit.
-
-    You can install GNU GLOBAL without rebuilding the PHP parser
-    (and instead use the parser distributed by GNU GLOBAL) by using
-    the option '--without-rebuilding-php-parser':
-
-      brew install global --without-rebuilding-php-parser
-
-    Use i.e. if you want to be sure whether a problem is caused by
-    the rebuild parser or some other thing in GNU GLOBAL.
