When building with W=1:
arch/m68k/math-emu/fp_arith.c:301:16: warning: no previous prototype for ‘fp_fsglmul’ [-Wmissing-prototypes]
301 | struct fp_ext *fp_fsglmul(struct fp_ext *dest, struct fp_ext *src)
| ^~~~~~~~~~
arch/m68k/math-emu/fp_arith.c:357:16: warning: no previous prototype for ‘fp_fsgldiv’ [-Wmissing-prototypes]
357 | struct fp_ext *fp_fsgldiv(struct fp_ext *dest, struct fp_ext *src)
| ^~~~~~~~~~
CC arch/m68k/math-emu/fp_log.o
...
Fix this by adding the missing prototypes to header files.
