Bug in collect2.c

[pavenis@lanet.lv]

There is small bug in collect2.c that appears in some conditions when 
DIR_SEPARATOR_2 is used for example in MS-DOS (target 
i[34567]6-pc-msdosdjgpp):
	
	when in MS-DOS path contains root directory of some drive
	(eg. C:\) wrong directory prefix is generated as no test is done for
	DIR_SEPARATOR_2. As result a lookup for something like 
	C:\/ld.exe causes Win9X to wait for rather long time 

Included patch fixes the problem (patch is against gcc-2.95.1)
