[Bug target/96532] [m68k] gcc 10.x generates calls to memset even for very small amounts

--- Comment #4 from Thorsten Otto <ad...@tho-otto.de> ---
Might be caused by x86 and s390 having a machine dependant pattern for
setmem/cpymem, possibly eliminating the library call again, while other
target's don't have such a pattern.
