Testing on Windows CE didn't show up any new problems.

Attached are the patches to use solib-target.c on WinCE, and a small fix to
gdbserver/win32-low.c to get toolhelp from toolhelp.dll instead
of coredll.dll - not your fault, the version I sent you had it wrong.

I had a problem building solib-target.c that I'm reporting in
another thread.

gdb/
	* arm-wince-tdep.c (arm_wince_init_abi): Remove svr4 related calls.
	* config/arm/wince.mt (TDEPFILES): Remove solib-legacy.o and
	solib-svr4.o, and add solib-target.o

gdb/gdbserver/
	* win32-low.c (load_toolhelp) [_WIN32_WCE]: Load functions from
	TOOLHELP.DLL.
