Patch: https://gcc.gnu.org/pipermail/gcc-patches/2021-January/563862.html

A workaround until the patch is approved, is to move the warning suppression
pragmas above the the function declaration.

My patches for pr98664 and pr98465 seem to also fix this.

--- Comment #1 from Martin Sebor  ---
The warning looks for the location into which the memchr caller was inlined (to
see if the caller is defined in a system header but itself called from user
code).  Without the alias it doesn't find one (because the caller isn't called
from anywhere) but with the alias it finds the memchr caller, __rawmemchr_ppc.
