Thanks to Eric Pouech, I have found some of the reason. Let's have a 
look at the following code:

extern void init(void) __attribute__((section(".init")));
extern void fini(void) __attribute__((section(".fini")));

main()
{
	printf("%s\n", __FUNCTION__);
}

asm("\n.section\t.init, \"ax\"\n"
    "\tcall init\n"
    "\t.previous\n");

asm("\n.section\t.fini, \"ax\"\n"
    "\tcall fini\n"
    "\t.previous\n");

void init(void)
{
	printf("%s\n", __FUNCTION__);
}

void fini(void)
{
	printf("%s\n", __FUNCTION__);
}

On FreeBSD, the output is like as follows:

init
init
main
fini
fini

Functions in the .init and .fini sections are automatically
executed at the init and exit time, respectively. 

On the other hand, on NetBSD they are just ignored (without compile
error) and never called. For details, see

  http://www.winehq.com/hypermail/wine-devel/2001/05/0021.html

For now I suspect that it's a bug of ld(1) or ld.elf_so(1).
