ver_linux: libcpp, fix missing output

Browse Source 
Neither 'libg++.so', nor 'libstdc++.so' were found where the current
implementation expects them to be found in the distros below.

Gentoo Linux
Debian 6.0.10
Oracle Linux Server release 7.1

Which results in zero ouput generated.

The proposed implementation relies on 'ldconfig' to locate the libraries
in question.  'Sed' is used to do the text processing.
