This broke arm-bsd or --enable-targets=all builds:

In file included from ../../src/gdb/armnbsd-tdep.c:26:
../../src/gdb/arm-tdep.h:315: error: ‘struct address_space’ declared inside parameter list
../../src/gdb/arm-tdep.h:315: error: its scope is only this definition or declaration, which is probably not what you want

I've applied the obvious fix below.
