binutils: fix out of tree building with syslex regens

If you take a release tarball (which has pregenerated syslex and sysinfo files
in it), apply some patches which touch syslex.l, and then build the result out
of tree, it will fail.  This is because syslex.l uses sysinfo.h, but the
sysinfo.y file wasn't updated and so it wasn't regenerated (the files are found
in the $srcdir), and the build rule for syslex.c does not use -I$(srcdir) when
it finds a local file.  Simple fix below.

[powerpc] crash trying to allocate memory in inferior

Our testsuite noticed a crash when trying to call a function which
requires GDB to allocate memory in the inferior. Typically, this
happens when one of the parameters is a string.  For instance, our
testcase tries:

    (gdb) call debug.trace (me, "You")
    [1]    32737 segmentation fault /path/to/gdb

What happens is that GDB sees the string, and thus tries to allocate
memory for it in the inferior:

> /* Allocate NBYTES of space in the inferior using the inferior's
>    malloc and return a value that is a pointer to the allocated
>    space.  */
>
> struct value *
> value_allocate_space_in_inferior (int len)
> {
>   struct objfile *objf;
>   struct value *val = find_function_in_inferior ("malloc", &objf);

And find_function_in_inferior first searches the symtab in case
we have debug info.  But, in our case (bareboard powerpc), we don't,
so it gets "malloc"'s address from the minimal symbols, and builds
a value whose type is a TYPE_CODE_PTR, not a TYPE_CODE_FUNC.

As a result, when we later try to make the call to malloc, we end up
inside the powerpc tdep code that has:

> do_ppc_sysv_return_value (struct gdbarch *gdbarch, struct type *func_type,
[...]
>   if (func_type
>       && TYPE_CALLING_CONVENTION (func_type) == DW_CC_GDB_IBM_OpenCL)

The problem is that func_type is not a TYPE_CODE_FUNC, and thus
the type-specific kind is not TYPE_SPECIFIC_FUNC, and so we do
TYPE_CALLING_CONVENTION is an invalid access.

Interestingly, the other call to TYPE_CALLING_CONVENTION is correctly
preceded by a check of the type's TYPE_CODE (making sure that it is
TYPE_CODE_FUNC).

gdb/ChangeLog:

        FUNC_TYPE's calling convention if FUNC_TYPE is not a function.

[Ada] Fix number of lines in -ada-task-info output

When using the new -ada-task-info command with an argument,
the output would say that there are N entries in the returned
table, (where N is the total number of tasks present in the inferior).
But, in fact, the table would only contain at most 1 entry.

This patch fixes this by properly computing the number of
tasks being displayed before giving it to the uiout.
