>Originator:     Izumi Tsutsui
>Release:        NetBSD 3.99.11
>Organization:
>Environment:
NetBSD/i386, but possibly affects all ports.
>Description:
src/libexec/ld.elf_so/Makefile explicitly sets DBG=-O3 -fomit-frame-pointer ,
but on some ports gcc -O3 may be problematic so it shouldn't be
specified by defaut.

>How-To-Repeat:
Code inspection.

>Fix:
Override DBG only on ports whose gcc -O3 is confirmed working properly.
At least, ports which have DBG=-O (not -O2) by default shouldn't use -O3
here.
