std_limits.h [...]: Define appropriate long double limits for m68k extended floating point.

	* include/bits/std_limits.h [__glibcpp_long_double_bits == 96]:
	Define appropriate long double limits for m68k extended floating
	point.
	(__glibcpp_f32_digits10): Corrected, off by one.
	(__glibcpp_f80_digits10): Likewise.
	(__glibcpp_f128_digits10): Likewise.
	* config/os/gnu-linux/bits/os_defines.h
	(__glibcpp_long_double_bits) [__mc68000__]: Define to 96.
