saveds/fbaserel warning with gcc6

[wawatok]

compiing m68k target (make OS=os3) with m68k-amigaos-gcc (GCC) 6.5.0b
i encounter a number of warnings like that:
private.h:247:126: warning: `saveds' attribute is only usable with fbaserel [-Wattributes]
d2, LONG), REG(d3, LONG flags), REG(a0, struct BitMap *));

perhaps -fbaserel should be added to gcc option, eventually after compiler/version detection.

[wawatok]

other than that there is also a number of:
../include/mccinit.c:712:37: warning: pointer targets in initialization differ in signedness [-Wpointer-sign]
if((DOSBase = (struct DosLibrary*)OpenLibrary("dos.library", 39)) &&
this is probably not critical, but i can provide a whole log of these if necessary

[wawatok]

fwiw, here is a compile log after -fbaserel has been added to mcc and mcp cflags:
