Your problem is two fold:

	- someone has put libresolv.a in libc.a, probably because
	  he put the resolver in libc.so.* too.
	- The resolver library is compiled with -pic, so that
	  sun users can put it in libc.so.*.

GNU ld doesn't understand objectfiles compiled with -pic.
The gcc installation should use collect and the native
linker, rather than GNU ld.
