Does /home/lucier/programs/gcc/objdirs/mainline/./prev-gcc/g++ exist,
and if yes, is it a functioning executable?
If it doesn't exist, that looks like the toplevel logic for which
languages to build still has a loop hole for --enable-languages=c,
either not properly enabling the C++ compiler for stage 1, or wrongly
overriding CXX, CXX_FOR_BUILD in toplevel Makefile.tpl to point to
nonexistent previous-stage C++ compiler. I don't know which is the
desired one.
BTW, what's the last <stuff omitted>, and why does your /lib/cpp try to
spawn cc1plus?
Cheers,
