re: lib/54449: _pic.a libraries contain unwanted debug information

not sure what planet you are talking about, but DBG=-g has been
the right way to me for a long time, though slightly less than
i recalled (more a 90s thing :-)

Allow optimizer/debug flags to be changed on command line without
breaking everything.  Eg. use DBG="-O0 -g" when debugging something.

nothing is an accident when "DBG=-g" builds have debug info.

i used to build my whole systems this way without using MKDEBUG
(since that's much much newer), initially because i had some 
lossage using separate debug info files, though as i mentioned
before, i'm considering switching back to get debug symbols back
in to my static libraries as well.  i may have to set execmax
to some very low value to avoid the other bug..

i claim that their lack of debug info is a bug in MKDEBUG.
