Subject: [PATCH v3] scripts/gdb: fix lx-version

For current gdb version (has 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
Linux version 4.19.0-rc1+ (changbin@...r) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #21 SMP Sat Sep 1 21:43:30 CST 2018
