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:
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?
