Patch for rtld.c

[Andreas Jaeger]

I've read today through rtld.c and noticed that we have a check for
_dl_rtld_map.l_opencount > 0 in dl_main but initialize it to 1. 

Looking closer together with Andreas Schwab, he found that the
following change changed one place where l_opencount was incremented
- but this place was forgotten:

1998-05-03  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* elf/rtld.c (dl_main): Fix check for number of references to
	interpreter object.

I'm appending a patch to fix this (l_opencount == 1 means there's no
explicit ref).

	* elf/rtld.c (dl_main): Fix check for references to dynamic
	linker.
