Sorry for the late reply, but I had to collect various evidences for my
sayings and my development machine is reaaaaaaaaaaally slow.
In fact it seems the toolchain built for buildworld contains a ld(1)
binary which invariably bases lookups for libraries in ${WORLDTMP}, even
in case of an absolute path. I have two evidences of this:
- Putting /usr/obj/usr/src/tmp/usr/lib/libssp_nonshared.a in
/usr/obj/usr/src/tmp/usr/lib/libc.ld leads toolchain's ld(1) to use
/usr/obj/usr/src/tmp/usr/obj/usr/src/tmp/usr/lib/libssp_nonshared.a;
- I also verified this with a hand-wrought opensnoop-like DTrace script.
If it's enough for you, can you please go forward and commit my patch?
I can make a cleaner one if you want.
Thanks.
