* Makefile.in: Add i386lynx-tdep to the right places.

(TARDIRS):  Add gdbserver.

* exec.c (print_section_info):  Print entry point.
* i386lynx-nat.c (i386lynx_saved_pc_after_call):  Move into
i386lynx-tdep.c.  Add core file support.
* i386lynx-tdep.c:  New module for Lynx/386 target dependant code.
* maint.c:  Add `maint info sections' command to print info about all
sections that BFD knows about for exec and core files.
* sparc-tdep.c (sparc_push_dummy_frame):  Update stack pointer
before putting frame on the stack.  Consolidate writes to reduce
traffic for remote debugging.
* config/i386/i386lynx.mh (NATDEPFILES):  Remove exec.o.
* config/i386/i386lynx.mt (TDEPFILES):  Add exec.o, i386lynx-tdep.o.
* config/i386/nm-i386lynx.h:  Add target_pid_to_str().
* config/i386/tm-i386lynx.h:  Remove target_pid_to_str().
* sparclite/Makefile.in:  Add deps to keep Sun make happy.
