Fix inferior memory reading in GDBServer for arm/aarch32
Before this patch, some functions would read the inferior memory with
(*the_target)->read_memory, which returns the raw memory, rather than the
shadowed memory.
This is wrong since these functions do not expect to read a breakpoint
instruction and can lead to invalid behavior.
Use of raw memory in get_next_pcs_read_memory_unsigned_integer for example
could lead to get_next_pc returning an invalid pc.
Here's how this would happen:
In non-stop:
the user issues:
thread 1
step&
thread 2
step&
thread 3
step&
In a similar way as non-stop-fair-events.exp (threads are looping).
GDBServer:
linux_resume is called
GDBServer has pending events,
threads are not resumed and single-step breakpoint for thread 1 not installed.
linux_wait_1 is called with a pending event on thread 2 at pc A
GDBServer handles the event and calls proceed_all_lwps
This calls proceed_one_lwp and installs single-step breakpoints on all
the threads that need one.
Now since thread 1 needs to install a single-step breakpoint and is at pc B
(different than thread 2), a step-over is not initiated and get_next_pc
is called to figure out the next instruction from pc B.
However it may just be that thread 3 as a single step breakpoint at pc
B. And thus get_next_pc fails.
This situation is tested with non-stop-fair-events.exp.
In other words, single-step breakpoints are installed in proceed_one_lwp
for each thread. GDBserver proceeds two threads for resume_step, as
requested by GDB, and the thread proceeded later may see the single-step
breakpoints installed for the thread proceeded just now.
Tested on gdbserver-native/-m{thumb,arm} no regressions.

Run more ld tests when not native
Many of the ld tests are not run for cross builds, in some cases
because the test needs to run a newly linked executable, and in others
simply because it was easier to write the test for native only. Even
when a test needs to run, it's good to compile and link to exercise
the linker. So that's what this patch does. I've also rid us of
the old ld_link procedure with all the HOSTING_CRT0 etc. setup. It's
much simpler to just link with $CC.

Return 'int' rather than 'unsigned short' in avrdis_opcode
avrdis_opcode return type is unsigned short, but -1 at the end of
this function is returned. Additionally, print_insn_avr doesn't
handle when -1 (in case of memory error) is returned from
avrdis_opcode.
This patch changes avrdis_opcode returning int indicating the error,
and adds a new argument for instruction we got on success. The
opcode is 16-bit, so I change local variables type to uint16_t,
and include "bfd_stdint.h" as a result. On memory error,
print_insn_avr returns -1, which is a common convention among most
of print_insn_$ARCH functions.
