Thank you! I've known to how to create a *compat* PIC library, firstly using
`-fvisibility=hidden' in compile command line to hidden all symbols, then
using `objcopy -R' to remove .got section totally! However, assemble result is
just like this

	call	__i686.get_pc_thunk.bx
	addl	$_GLOBAL_OFFSET_TABLE_, %ebx // << A.
	...
	movl	%eax, g@GOTOFF(%ebx) // << B.

It seems gcc should do better since both A and B are const, so it's safe to
remove line A as my idea shows.
