Hello,

When running a program on the powerpc-elf simulator, I get the following
warning:

(gdb) run
Starting program: /[...]/ex/other
!!! -> warning: no shared library support for this OS / ABI

Breakpoint 1, other () at other.adb:12
12 end Other;

After having a look, it appears to be a side-effect of a patch
that moved the post-target_create_inferior processing from the
target layer back to the core layer. I think the interesting
part of the ChangeLog entry is the following:

* infcmd.c (post_create_inferior): Call solib_add,
solib_create_inferior_hook, and re_enable_breakpoints_in_shlibs.

Before this change was made the remote-sim code was in charge
of doing that, and this code was not calling the solib create_inferior
hook.

In the case of powerpc-elf, GDB links in solib.c and solib-svr4.c.
I don't think the bareboard case is supported by these units, so
I think the sensible thing to do is to remove them from the closure
and not build them.

Opinions?

* config/powerpc/ppc-sim.mt (TDEPFILES): Remove solib.o and
solib-svr4.o.

Is it possible to run the testsuite? The compilers I have use the
powerpc-elf- prefix (eg: powerpc-elf-gcc).

Thanks,
