The makefile in input/regression/ collects all regtests in the variable 
COLLATED_FILES. For an out-of-source build, each regtest will have the 
absolute path, which for a gub build was >130 characters for the source 
directory. 

Now the problem is that we have >1000 regtests, each of which has an absolute 
path >131 chars. As a consequence the list in COLLATED_FILES had more than 
131000 characters, which was then passed to the lys-to-tely script on the 
command line. 
On the other hand, the Linux kernel allows the command line to have a maximum 
length of a little more than 131000 characters...

So the build of the regtests failed in make, since it couldn't execute the 
lys-to-tely call.

Cheers,
Reinhold
