Bootstrap build problem after V8 test-in-container patch".

[Steve Ellcey <sellcey at cavium dot com>]

I am having a build problem after DJ's patch "V8 test-in-container patch".

I do a bootstrap build by building binutils, then I build a 'partial gcc'
by building "all-gcc all-target-libgcc" and
"install-gcc install-target-libgcc", then I build glibc using that gcc,
followed by a complete build of gcc.

This is no longer working for me, because the glibc build fails with:

aarch64-linux-gnu-gcc -mabi=lp64 -nostdlib -nostartfiles -o /home/sellcey/tot/obj/glibc64/support/links-dso-program .....

/home/sellcey/tot/install/lib/gcc/aarch64-linux-gnu/9.0.0/../../../../aarch64-linux-gnu/bin/ld: cannot find -lstdc++

I tried updating my 'initial' gcc build to include all-target-libstdc++-v3
and install-target-libstdc++-v3 and to include c++ in the languages that
are configured but when I do that the initial gcc build fails during the
configuration of libgomp (presumably libstdc++ needs libgomp).  The libgomp
configure fails with:

/home/sellcey/tot/install/aarch64-linux-gnu/bin/ld: cannot find crt1.o: No such 
file or directory
/home/sellcey/tot/install/aarch64-linux-gnu/bin/ld: cannot find crti.o: No such 
file or directory

I think this failure to be able to do a bootstrap build is going to be a
problem, has anyone else run into this?  Does anyone have a fix?
