The following change broke simulator testsuite with host GCC 13:
commit 435ad222b3de93fa647fba7221eece36b1b395eb
sim: warnings: compile build tools with -Werror too
Host GCC13 complains about missing function prototypes:
binutils/sim/testsuite/common/bits-gen.c:26:1: error: no previous prototype for ‘gen_struct’ [-Werror=missing-prototypes]
26 | gen_struct (void)
| ^~~~~~~~~~
Fix by making the functions static, which instructs the compiler that
there is no need for a prototype.
