- Subject: Building cross-gdb to arm-netbsd
Building a cross gdb to arm-netbsd fails. There are a few functions
in breakpoint.c which are only defined if SOLIB_ADD is defined. For
arm-netbsd, SOLIB_ADD is normally defined by solib.h. For a native
arm-netbsd build, solib.h is included (indirectly) by the NAT_FILE
config/arm/nm-nbsd.h. However, this does not happen for a cross gdb
to arm-netbsd.
For example, clear_solib() in solib.c calls
disable_breakpoints_in_shlibs(), which is only defined in breakpoint.c
if SOLIB_ADD is defined. solib.o appears in TDEPFILES in
config/arm/nbsd.mt, which I think is correct for this target.
I don't know how the solib.h thing is supposed to be handled in the
multi-arch regime. Presumably it is wrong for breakpoint.c to only
define functions based on SOLIB_ADD.
In any case, this patch fixes the build problem. It reverses part of
this change, because it resurrects config/arm/tm-nbsd.h.

* configure.tgt (arm*-*-netbsd*): This variant is now fully multi-arch.
* config/arm/nbsd.mt (TM_FILE): Delete.
* config/arm/tm-nbsd.h: Delete.
So I don't know if this patch is correct. But either this patch, or
some different fix, should be applied.

* config/arm/nbsd.mt (TM_FILE): Define.
* config/arm/tm-nbsd.h: New file.
