_dll_crt0: Drop incorrect check for being started from parent main thread
This test was broken from the start. It leads to creating a completely

the main thread of the parent. However, the main thread of a process
can easily running on a completely different stack, if the parent's main
thread was created by calling fork() from a pthread. For an example,
