I think I didn't explain the problem correctly, sorry.
We indeed already have WITH_SSP/WITHOUT_SSP knob which is turned into
MK_SSP="yes" or MK_SSP="no" respectively.
The actual problem lies in Makefiles that define WITHOUT_SSP for some
reason. For instance, in Makefile.inc1 the toolchain (namely
bootstrap-tools, build-tools, cross-tools and a few other things) is
built without SSP thanks to -DWITHOUT_SSP. For example:
224 BMAKE= MAKEOBJDIRPREFIX=${WORLDTMP} \
225 ${BMAKEENV} ${MAKE} -f Makefile.inc1 \
226 DESTDIR= \
227 BOOTSTRAPPING=${OSRELDATE} \
228 -DWITHOUT_SSP \
229 -DWITHOUT_HTML -DWITHOUT_INFO -DNO_LINT -DWITHOUT_MAN \
230 -DWITHOUT_NLS -DNO_PIC -DWITHOUT_PROFILE -DNO_SHARED \
231 -DNO_CPU_CFLAGS -DNO_WARNS -DNO_CTF
There is a problem is the user defines WITH_SSP in src.conf or on
command-line. In this case, bsd.own.mk screams because both WITH_SSP
and WITHOUT_SSP are defined. Try to make buildworld with -DWITH_SSP,
and it won't even fill your terminal before breaking :).
That's why my proposition was to introduce NO_SSP, that could be used
from those Makefiles instead of WITHOUT_SSP to work around the
bsd.own.mk checks. But there may be a wiser or neater solution I can't
devise by myself, that's why I'm asking.
Thanks for your help.
