Actually, this is mostly a linux/gcc problem. i am compiling aolserver since a while with tcl-8.5 (mimimum Tcl 8.5.1 required), but mostly under Mac OS X, so i have not seen the problem.
However, notice that nsconfig.tcl calls as well configure. configure.in has a similar section about LDLIB (if it contains *gcc* or *shared*, the flag "-nostartfiles" is added). So, it is essentially the same mechanism as in 4.0. What is the value of LDLIB on your system?
