GCC 5.4 sparc problems

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

I finally got around to booting one of my SPARCstation 5s with the latest
-current (7.99.32) built with GCC 5.4.

It mostly works, but there are a few problems:

Core was generated by `postconf'.

For 'amd' and 'sshd', the parent process did not crash and remained
running.

"security/sudo" built from pkgsrc-2016Q1 with GCC 4.8.5 still works.
I haven't tried anything else yet.
