>Description:
	After updating kernel and userland, the compiler can no longer compile
	c++ programs, but complains about undefined references.
	Look at "g++ -dumpspecs" output and see that the missing symbols have
	been split off into libgcc_eh.a but the compiler doesn't pass this
	library to the linker.

bash-2.05b$ cat test.cxx 
#include <iostream>
using namespace std;
int main() {
  cout << "Hello world." << endl;
}
bash-2.05b$ g++ test.cxx
