[oe] [PATCH] gcc 4.1.2: fix dependency_libs for libstdc++ and libsupc++

[Frans Meulenbroeks]

This fixes a QA issue in gcc 4.1.2.
The patch is identical to what is done in gcc 4.2.2 and 4.2.4
The issues caused neek compilations to fail

NOTE: gcc 4.1.0 4.1.1 4.2.1 4.2.3 are also missing this patch.
Can't easily test those now so not submitting a patch for these.
and maybe the patch is also needed for gcc 4.0.*
No idea about gcc3.
