Subject: [PATCH] Use full path to dnsdomainname and domainname in 
	scripts/mkcompile_h

With reference to: http://bugzilla.kernel.org/show_bug.cgi?id=14920
I'll post my suggestion here.

Currently scripts/mkcompile_h checks for "/bin/dnsdomainname" and
"/bin/domainname" when trying to find the DNS name.
Though, when running the executable - the full path isn't used!

IMO if we check for "/bin/dnsdomainname", we should also use
"/bin/dnsdomainname" - and not blindly trust /bin is the first directory in
$PATH  which contains a executable named "dnsdomainname"


I propose to use the full path, that we know is valid. Here's my proposed patch:
