* config/m68k/m68k.h (LONG_DOUBLE_TYPE_SIZE): Make 64-bit on ColdFire.
(LIBGCC2_LONG_DOUBLE_TYPE_SIZE): Likewise.
* config/m68k/netbsd-elf.h (LIBGCC2_LONG_DOUBLE_TYPE_SIZE): Undefine
before redefining.
* config/m68k/uclinux-oldabi.h (LONG_DOUBLE_TYPE_SIZE): Redefine to
80 unconditionally.
(LIBGCC2_LONG_DOUBLE_TYPE_SIZE): Likewise.
