Now I get it. You cannot update the md5sum for gdbserver with
'--update-md5'. You need to do it manually. gdb and gdbserver share the
md5sum and the kconfig symbol is PTXCONF_GDB_MD5. Run
"md5sum /home/clemens/shared-src/gdb-7.11.1.tar.gz" and enter the result in
'ptxdist menuconfig' or edit the ptxconfig manually to update
PTXCONF_GDB_MD5.
