PATCH: minor cleanup to dwarf2read.c

[Jim Blandy <jimb@zwingli.cygnus.com>]

2001-07-03  Jim Blandy  <jimb@redhat.com>

	* dwarf2read.c (dwarf2_build_psymtabs_hard): Remove extraneous
	code in loop condition.  This seemed to be trying to round
	info_ptr up to the next four-byte boundary, but that's not what it
	actually did.  If we discover the problem the old code was really
	trying to address, we can fix it properly.
