[Bug build/11250] New: C files generated from XML have garbage

["hjl dot tools at gmail dot com" <sourceware-bugzilla at sourceware dot org>]

When I ran

/export/build/gnu/gdb-avx/build-x86_64-linux/gdb/gdb -nx -q -batch -ex "set
tdesc filename i386/x86-64.xml" -ex 'maint print c-tdesc' > x86-64.c

I got

^[[?1034h/* THIS FILE IS GENERATED.  Original: x86-64.xml */

at the beginning of the file. It is caused by:

#0  0x000000326a46dd70 in putc () from /lib64/libc.so.6

gdb tries to initialize readline which prints out chars only
valid for TUI.
