Fix build for OLD_FREEBSD_ABI_LABEL

	PR ld/17440
	* elf32-i386.c (elf_i386_fbsd_post_process_headers): Fix build
	for OLD_FREEBSD_ABI_LABEL.
Fix library-list.dtd -> library-list-svr4.dtd

commit 2268b414f486239cbcc0f756f157c3e03599efac
added file "features/library-list-svr4.dtd" but the added code uses
"library-list.dtd" instead.

Curiously after changing for a test s/name/nXme/ in the DTD making the
gdbserver output non-conforming there is no warning or regression seen (tested
gdb.base/shlib-call.exp, using_xfer is still 1).  I did not check more why the
DTD conformance verification does not work.

Skip dlopen-libpthread.exp in cross testing

I see the following fails on arm-linux-gnueabi,

result of ldd build-git/arm/gdb/testsuite/gdb.threads/dlopen-libpthread.so is 1
output of ldd build-git/arm/gdb/testsuite/gdb.threads/dlopen-libpthread.so is not a dynamic executable
child process exited abnormally
FAIL: gdb.threads/dlopen-libpthread.exp: ldd dlopen-libpthread.so
FAIL: gdb.threads/dlopen-libpthread.exp: ldd dlopen-libpthread.so output contains libs

the test script invokes ldd (on host) for the target libraries, which
is wrong.  ldd can't be cross because it invokes dynamic linker with
LD_TRACE_LOADED_OBJECTS and gets the dependent libraries.  My first
reaction to this problem is to execute ld.so on the target (like
remote_exec target).  When I start to hack proc build_executable_own_libs,
I find it has assumptions here and there that the native testing is
performed.  Then I check the callers of build_executable_own_libs,
and they are all skipped if isnative is false.  It is reasonable to do
the same in dlopen-libpthread.exp too.

[Patch, microblaze]: Add wdc.ext.clear and wdc.ext.flush insns

Added two new instructions, wdc.ext.clear and wdc.ext.flush,
to enable MicroBlaze to flush an external cache, which is
used with the new coherency support for multiprocessing.

[Patch, microblaze]: Add initial port of linux gdbserver

add gdb_proc_service_h to gdbserver microblaze-linux

gdbserver needs to initialise the microblaze registers

other archs use this step to run a *_arch_setup() to carry out all
architecture specific setup - may need to add in future

 * add linux-ptrace.o to gdbserver configure
 * gdb/configure.tgt: Set build_gdbserver=yes
 * Update breakpoint opcode
 * fix segfault on connecting gdbserver
 * add microblaze_linux_memory_remove_breakpoint
 * add set_solib_svr4_fetch_link_map_offsets
 * add set_gdbarch_fetch_tls_load_module_address
 * Force reading of r0 as 0, prevent stores

[Patch, microblaze]: Added Backtrace support to GDB

Added backtrace support without debugging information.

Earlier backtrace used to work only when debug information is available.
Previous pc & sp values are calculated incorrectly due to which backtrace
was failing.

In this patch, previous frame sp & pc values are calculated correctly
in microblaze_frame_cache function and supplied them to
microblaze_frame_prev_register function
