[src/trunk]: src/sys/arch fix various gcc6 m68k issues:
details: https://anonhg.NetBSD.org/src/rev/b411eef748b0
branches: trunk
changeset: 831024:b411eef748b0
user: mrg <mrg%NetBSD.org@localhost>

description:
fix various gcc6 m68k issues:
- bad indentation. next68k en.c and mvme68k le_poll.c fixes real issues
in error handling, the rest are NFCI.
- pass 68030 flags as appropriate for mvme68k.
- next68k nextrom.c has -Warray-bounds ignored for an odd expression
that appears to run before relocation, and needs manual offsets
added which trips bounds array checking.
with this all m68k ports build with GCC 6.
