I would like to know how it is possible to know the current system architecture in GDB and store this information into a variable for later evaluation.

Something like: 

set variable $x=`shell uname -m`

theres 2 ways:

the older way:

(gdb) shell echo set \$x=\"$(uname -m)\" >/tmp/foo.gdb
(gdb) source /tmp/foo.gdb

newer with python:

(gdb) python gdb.execute("set $y=\"" + os.uname()[4] + "\"")
