Ok, let me clarify somethings:
1) libstdc++.so and libgcc_s.so are not development libraries
A) Ok, I understand this. These are/will not be available on my
deployed system, though.
2) C binaries have no dependency on libgcc_s
A) There was once a dependency on libgcc_s for C binaries but I
found on another website on how to tweak the 'specs' file to
prevent this. These C binaries work just fine on the deployed
system. With all other internal libraries being statically linked
in.
3) at the moment I am just trying to build our shared libraries and I am
hoping that I can remove the libstdc++ and the libgcc_s dependencies
from.
