New bug list policy

[Torbjörn Granlund]

Almost all mail to this list contains very poor bug reports,
such as a dump of a line

  FAIL: t-foo

without any hint of platform/compiler, or else reports where the user
cannot compile anything, or reports about the ancient GMP 4.3.2.

These reports are just list and archive noise, and therefore we will no
longer forward such messages to this list.  Instead moderators will
reject the reports with a short message.
