That does describe the reason why dl* symbols are included in crt0.
But doesn't describe the reason why dl* symbol definitions cannot be 
moved from crt0 to libc.

Please re-read original description of the problem:
http://mail-index.netbsd.org/tech-userlevel/2000/02/23/0000.html

As the orignal mail describes, currently libc functions cannot call
dlopen(3) and related functions on ELF platforms.
Please note that locale(3) implementation have to call dl*(3)
functions (like commercial UNIXes).

What is the best way to solve this problem?
