Hi,

the message should not be private. Seems that I need a short "How to
use a Mailinglist" ;-) too. 

As I am also facing a new bild run an I don't want to have the same
troubles : Your solution is much more smarter than my old one (
https://sourceware.org/ml/crossgcc/2015-04/msg00008.html  ). Is there
already more support form the 300-gdb script or didn't I find the easy
solution? Anything else worked out of the box?

Regards
Thomas
