[Bug gold/10875] New: links against libraries I never have specified

[robert dot wohlrab at gmx dot de]

I tested different packages in debian and noticed that gold always links
against some libraries which aren't used and I never specified. I also tested
to use --as-needed and it didn't change that weird behavior. This doesn't
happen with the old binutils linker

Example output from zlib:

dpkg-shlibdeps: warning: dependency on libgcc_s.so.1 could be avoided if
"debian/zlib1g/usr/lib/libz.so.1.2.3.3" were not 
uselessly linked against it (they use none of its symbols).                     
dpkg-shlibdeps: warning: dependency on ld-linux-x86-64.so.2 could be avoided if
"debian/zlib1g/usr/lib/libz.so.1.2.3.3" were

dpkg-shlibdeps: warning: dependency on libgcc_s.so.1 could be avoided if

I had also a different package which also linked against libICE without any
visible reason, but cannot find it again at the moment
