daily update

py-inferior.exp: Make sure local var is allocated on the stack.

The testcase, at some point, is trying to change the contents
of a string that was defined as follow:

    char *str = "hello, testsuite";

The problem is that the string is constant, and str is never used
to change the contents of the string in the program, so the compiler
is free to allocate it in a read-only section.  This is what happens
on x86-windows, for instance.

As a result, trying to change the contents of the string during
the `python gdb.inferiors()[0].write_memory (addr, str)' results
in the following error:

    (gdb) python gdb.inferiors()[0].write_memory (addr, str)
    gdb: write target memory, 5 bytes at 0x00403064
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
    gdb.MemoryError: Cannot access memory at address 0x403064
    Error while executing Python code.

This patch prevents this from happening by declaring str as an
array rather than a pointer.

gdb/testsuite/ChangeLog:

        * gdb.python/py-inferior.c (f2): Make str an array rather
        than a pointer.
        * gdb.python/py-inferior.exp: Adjust testcase accordingly.

ppc sim: Improve invalid option error message

This patch improves the error message when an invalid option is
detected, by also printing the option that actually caused the error.
For instance, from GDB:

        (gdb) target sim --hello
        Invalid option: --hello
        Usage:
        [...]

We also added the usage after an invalid long-name option (Eg: --hello)
to be in line with what's being done for all other invalid options
being detected.

sim/ppc/ChangeLog:

        * psim.c (psim_options): Add option that cause the error
        in invalid-option error messages. Print the usage when
        detecting an invalid long-name option.

ppc sim: Allow --sysroot command-line option

There was a recent change that cuased the "target sim" command
to add a --sysroot option to the argument vector passed down to
the simulator.  This caused a failure in the powerpc simulator,
as it did not recognize it.  This patch fixes the problem by adding
support for the --sysroot option (it ignores it).
