nullcl -x fail on linux

[mingodad]

Trying to compile this sample nullcl -x fib fib.nc:

import std.io;

int fib(int n)
{
    if(n < 2) return 1;
    return fib(n-1) + fib(n-2);
}

int rc = fib(32);

io.out << rc << io.endl;

return 0;

Fail on Linux due to undefined references to math lib, adding it to nullcl/main.cpp solves it:
