[PATCH] strace: Remove -std=gnu23 from ptests makefile to fix reproducibility

with updated ax_prog_cc_for_build.m4 macros, -std=gnu23 can be added to
CC_FOR_BUILD based upon what autoconf-2.73 detects gcc on host to support
which could vary depending upon build host. This gets into Makefile which
is shipped with ptests on tatget. Since we are on gcc-15 this option is
not really needed on target as gcc15 defaults to c23
