I've wrote a script gdb/syscalls/update-linux.sh that can be used to do 
the update automatically.  The idea being that target maintainers can 
run the script on their platform and do the update.

AFAICT, the previous approach was to generate directly from kernel 
sources.  The benefit there is that you don't need access to a specific 
platform to do the update (but you'd still need access to test I suppose).

[ FWIW, it seems the linux kernel migrated to some syscall.tbl approach, 
and perhaps generating from there could be an option. ]

Anyway, this script at least adds one option to do the update.

WDYT?

Thanks,
- Tom

[gdb] Update syscalls/{amd64,i386}-linux.xml

- Add a script syscalls/gen-header.py, based on syscalls/arm-linux.py.
- Add a script syscalls/update-linux.sh (alongside update-freebsd.sh and
  update-netbsd.sh).
- Use syscalls/update-linux.sh to update syscalls/{amd64,i386}-linux.xml.in.
- Regenerate syscalls/{amd64,i386}-linux.xml using syscalls/Makefile.

In gdb/syscalls/i386-linux.xml.in, updating has the following notable effect:
...
-  <syscall name="madvise1" number="220"/>
-  <syscall name="getdents64" number="221"/>
-  <syscall name="fcntl64" number="222"/>
+  <syscall name="getdents64" number="220"/>
+  <syscall name="fcntl64" number="221"/>
...

I've verified in ./arch/x86/entry/syscalls/syscall_32.tbl that the numbers are
correct.

Tested on x86_64-linux.
