Some distros (NixOS) have their build environment enable
-Werror=format-security by default for security/hardening reasons.
Currently fsx fails to build due to this:
fsx.c: In function 'prt':
fsx.c:215:18: error: format not a string literal and no format arguments [-Werror=format-security]
fprintf(stdout, buffer);
^
fsx.c:217:20: error: format not a string literal and no format arguments [-Werror=format-security]
fprintf(fsxlogf, buffer);
^
Indeed the compiler is correct here, if the message-to-be-printed were
to contain a '%', unpredictable things would happen. Fix this.
