>Description:
	We have a directory with a subdirectory named "as". Up to now
	compiling things at this place worked ok. After updating the
	kernel gcc fails with
		cc: installation problem, cannot exec `as': Is a directory
	Is returning EISDIR more correct then returning EACCES?
	But in any case I think it is pretty bogus where cc looks for it's
	programs and files. After doing a ktrace I found that cc looks for
		/usr/libexec/NetBSD/sparc/2.7.2/cc1
		/usr/libexec/NetBSD/sparc/cc1
		/usr/lib/gcc/NetBSD/sparc/2.7.2/cc1
		/usr/lib/gcc/NetBSD/sparc/cc1
		/usr/local/NetBSD/sparc/bin/NetBSD/sparc/2.7.2/cc1
		/usr/local/NetBSD/sparc/bin/cc1
		/usr/libexec/NetBSD/sparc/2.7.2/cc1
		/usr/libexec/cc1
	and so on. I think it should look for /usr/libexec/cc1 only.

>How-To-Repeat:
	$ cd /tmp
	$ mkdir as
	$ echo "main(){}" >xxx.c
	$ cc -o xxx xxx.c
