Converting inline __attribute__((format (printf,x,y) functions
to macros or statement expressions produces smaller objects

before:
$ size vmlinux
   text    data     bss     dec     hex filename
4716770  474560  618496 5809826  58a6a2 vmlinux
after:
$ size vmlinux
   text    data     bss     dec     hex filename
4716706  474560  618496 5809762  58a662 vmlinux
