src/sys/arch/sun2/conf: Makefile.sun2
Log Message:
Compile sun2 kernel with -fno-omit-frame-pointer for GCC8 as a work
around for reproducible kernel freezes just after ``Starting postfix.'',
where I cannot even enter DDB nor obtain crash dump.
I still haven't figured out why. Possibly something wrong with -Os
optimization level for GCC/m68k, cf.,
