server: gdb_server: fix memory map generation on a 32-bit BE host
Due to lack of printf format check wrong specifier was used and it
actually broke operation on a 32-bit BE host.
So fix this and add the necessary function attributes so that the bugs
like that can be uncovered automaticaly.
Reported and pinpointed by Karl Palsson on IRC.
