        * config/m68k/tm-m68k.h (NUM_FREGS): m68k-linux patch.
          Added NUM_FREGS macro.

        * config/m68k/xm-linux.h: m68k-linux patch. New file.

        * config/m68k/tm-linux.h: m68k-linux patch. New file.

        * config/m68k/nm-linux.h: m68k-linux patch. New file.

        * config/m68k/linux.mt: m68k-linux patch. New file.

        * config/m68k/linux.mh: m68k-linux patch. New file.

        * gdbserver/low-linux.c: m68k-linux patch. Added an ifdef
          that checks the value of __GLIBC to decide whether or
          not to include sys/reg.h.

        * m68klinux-nat.c: m68k-linux patch. New file. Note
          both m68k-tdep.c and m68klinux-nat.c contain definitions
          for supply_gregset and supply_fpregset. The definitions
          in m68k-tdep.c are valid is USE_PROC_FS is defined. Otherwise,
          the definitions in m68klinux-nat.c will be used. This is a
          bit of a hack. The supply_* routines do not belong in
          *_tdep.c files. But, there are several lynx ports that currently
          depend on these definitions.

        * configure.tgt: m68k-linux patch. Added m68*-*-linux*
          gdb_target.

        * configure.host: m68k-linux patch. Added m68*-*-linux*
          gdb_host.

        * Makefile.in: m68k-linux patch. Added compile line for
          m68klinux-nat.o
