Obsolete/broken targets in 4.0.0

[Eric Botcazou]

Hi Mark,

What is the procedure to mark a target as obsolete or to remove a broken 
target for 4.0.0?  Some SPARC targets (namely sparclite-elf, sparclite-coff, 
sparc86x-elf and sparc-openbsd) have been broken (do not build) since at 
least 2 releases (from 3.3 onwards).  Can I remove them from mainline or 
should they first go through a period of obsolescence?

Thanks in advance.
