A system C and C++ compiler is documented as a required dependency of

As such, I would argue that it's not worth declaring it up-front in
osdependencies
in all software that needs a system compiler, particularly as the package
will be named differently on different distros.
Thanks for pointing this out! I agree with you.
It's all too easy to miss the general EB prerequisites/dependencies when
installing a new node. I've added the CentOS 7 specifics to my EB Wiki
page:
https://wiki.fysik.dtu.dk/niflheim/EasyBuild_modules#easybuild-prerequisites
One easy thing we could do is make the binutils easyblock check whether
both 'gcc' and 'g++' are present, and emit a clear warning if they're
missing?
That would help significantly, since pinpointing the underlying problem
is clearly not trivial.
Not sure we should make that a hard failure though, as there may be
situation where not having gcc/g++ is actually fine (e.g. when 'cc' and
'c++' compilers are available, and can be used to compile binutils).
One other option could be to detect that the build failed because g++ is
not there (by recognizing the pattern in the configure output or in
config.log).
Same applies for GCC(core), where you also need a system C++ compiler
with sufficiently recent versions...

I guess that doing: "yum install gcc-c++" would solve the issue.
But I have not tested yet. But does it make sense to do that?
Your suggestion fixed the problem with binutils: yum install gcc-c++
Now it build correctly, and the foss-2019a build process is continuing.
What's the root cause of this issue? I'm guessing that the EB file
.../EasyBuild/3.8.1/lib/python2.7/site-packages/easybuild_easyconfigs-3.8.1-py2.7.egg/easybuild/easyconfigs/b/binutils/binutils-2.31.1.eb
must include gcc-c++ as an osdependencies package.
If this guess is correct, I could open an issue.
