Running on my other system I get:
equery b libstdc++.so.6
* Searching for libstdc++.so.6 ... sys-devel/gcc-4.5.4
(/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.4/libstdc++.so.6 ->

env-update - doesn't work either


Check beneath /etc/env.d/ld.so.conf.d and ensure that there is a file
defining the appropriate paths for your current version of gcc. Here's
how it looks on my system:

  # cd /etc/ld.so.conf.d
  # ls
  05binutils.conf  05gcc-x86_64-pc-linux-gnu.conf
  # cat 05gcc-x86_64-pc-linux-gnu.conf
  /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/32
  /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3

Once you have made any necessary changes, run ldconfig.

Thanks Kerin, for the pointer.
I think I have a bigger problem, and don't know how to fix it.

Yes, I have the same file /etc/ld.so.conf.d
# ls # 05gcc-x86_64-pc-linux-gnu.conf
# cat /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/32
/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3

However, those directories are empty (only one file):
# ls -al /usr/lib/
libbrcomplpr2.so

Is /usr/lib an actual directory or a symlink? Assuming that you use a
stock amd64 (multilib) profile, it should be a symlink to lib64. If you
find that it is a directory and that you also have a lib64 directory,
try the commands below. You can skip the busybox and exit commands if
you are doing this in a chroot rather than on a live system.

  # busybox sh
  # cd /usr/
  # mv lib lib.old
  # ln -s lib64 lib
  # exit

On my other working system this directory "/usr/lib/" contain about 2020
files.
What had happened?
After emerging some files and system I was running command: fstrim -v /
(as the disk is SSD).
Could it have something to do with the fact that these directories are
empty?

No. Using fstrim does not delete files.

Kerin you are a magician! THANK YOU!!!
Yes, it worked.  Everything is back to normal.

I can still not comprehend what had happened :-/ why all of a sudden in
the middle of compilation it all vanished.

Were you doing anything outside of portage that may have had a hand in it?

Incidentally, you should move libbrcomplpr2.so to /usr/lib32. Some googling suggests to me that it is a library included in a proprietary Brother printer driver package. You can use the file command to confirm that it is a 32-bit library.
