A bug is present in GDB which causes early string termination when
parsing variables. This has been reported [0], but we should ensure
that we can support at least basic printing of the core kernel strings.
For current gdb version (has been tested with 7.3 and 8.1), 'lx-version'
only prints one character.
(gdb) lx-version
L(gdb)
This can be fixed by casting 'linux_banner' as (char *).
(gdb) lx-version
