Finding runtest

[Richard Earnshaw <rearnsha at arm dot com>]

gdb comes with dejagnu as part of the distribution (to ensure we use one 
with the correct features).  Most of the time, the make system will pick 
this up automatically and use it in preference to any version that is 
installed on the path.  Unfortunately, this is not the case when checking 
dejagnu itself.  In this case, it will only work using a version that has 
already been installed.

The effect of this is that "make check" will fail when trying to check 
dejagnu if dejagnu has not been previously installed on the path.

I'm not entirely convinced that it is correct for a test program to be 
testing itself, but the current behaviour is a bit inconsistent.

Sorry no patch at the moment (I only came across this at home last night) 
and haven't had chance to fix it yet.
