They are stuck with pre-GPLv3 GCC compilers anyway.
ISTR we changed the default i?86 triple from i386 to i586 for 4.6, so we
are already half-way through the deprecation. I'd say simply go ahead.
Note that i386-freebsd is still listed as primary architecture though, so
something has to be done about that first. Steering Commitee please?
(I'd say drop *-freebsd from the list of primary/secondary archs entirely
given that they are not at all happy with GPLv3 and not using still maintained
compilers)
