I would've thought this was fixed in 2.4.x now.  You might try using newer 
sources.  The below patch fixes the issue:

As the original patch I found stated about gcc-3.4.x:

From: Jan Hubicka <jh@suse.cz>

GCC now converts sprintf (a,"%s",b) to strcpy.  This lose on kernel as
strcpy is not inlined and not present in library, so one gets linker
failure.  It seems to make sense to apply this optimization by hand.
