We are using patched gcc but it fail on gentoo's default compiler's to.
It works fine with GCC 4.2.4 and lower.
The fail file is part of libnet
the symbol that miss the @PLT is libnet_getgre_length
it sould have @PLT as the rest of the symbols
If i compile the fail file with -pic instead i compiles fine.
and have @PLT added
