The ch_type field in struct Chdr_data<64> is 4 bytes, followed by a
4-byte padding. This change doesn't introduce any functional change
since only the lower 32 bits of the ch_type field are used.

As reported by Ulrich here:
https://sourceware.org/ml/gdb-patches/2015-09/msg00604.html
The system compiler (gcc 4.1) in Centos 5 doesn't like that we cast to a
pointer to a type that doesn't exist. I see no real value in using this
kind iof construct over just using void *. So this patch changes the
tdep_info field to void * and removes the casts. Even in C++, we
should not need an explicit cast when assigning to a void *.
gdb/ChangeLog:
* gdbarch.sh (struct gdbarch_info): Change tdep_info's type to void *.
* gdbarch.h: Regenerate.
* i386-tdep.c (i386_gdbarch_init): Remove cast to

I noticed this while working on the test case. I believe it would make
sense to skip running the tests if the binary failed to build. Although
I would understand the opposite argument: if the binary does not build
for some reason, we probably want to know about it, and some catastrophic
failures in the tests might alarm us better than a timid "UNTESTED".
gdb/testsuite/ChangeLog:
* gdb.python/py-type.exp: Do not run tests if binaries fail to
build.
Architectures which use RETURN_VALUE_STRUCT_CONVENTION will have a
NULL return value after executing a finish command. See get_return_value()
in infcmd.c.
This patch avoids an eventual SIGSEV (caused by attempting to
derefrence a NULL pointer) by adding a suitable test to
finish_command_fsm_should_stop().
I encountered this problem while testing msp430:
(gdb) PASS: gdb.base/structs.exp: zed L<n> for finish; return 1 structs-tc
finish

record a NULL value.
