* gdbserver/Makefile.in (gdbserver): Use -lbsd.

	* gdbserver/remote-inflow{-sparc}.c (create_inferior):  Don't use a
	shell when running the child, as args have been expanded by the
	time we get here.  Simplify calling convention.
	* gdbserver/remote-server.c (main):  Use new calling convention
	for create_inferior, remove defunct code for coalescing argv.
	Remove extra calls to mywait(), as we no longer have to wade
	through a shell.
