gdb-19990209 snapshot fails to build with missing all target

[rodneybrown@pmsc.com]

Snapshot gdb-19990209 fails to build because of missing opcode/Makefile
all target, when configured on AIX-4.2.0, UnixWare 2.1.1 and SunOS 4.1.3.
NB - while I'm patching up rather than pulling down a full tar.gz, the brik -Cb
< gdb.crc
worked & I did (belatedly) run the postpatch scripts.

Further look at missing SOLIB_.* externals building on AIX-4.2.0
I think that the relevant defines could be copied straight from the
coff-solib.h and the include for xcoffsolib.h be pushed into a
config/ header file. The reason I haven't patched this in is that
gdb/eval.c includes xcofflib.h for a struct vmap definition.
gdb/eval.o is in gdb/Makefile COMMON_OBJS - this suggests to me that
the vmap definition needs to be separated out, since xcoffsolib.h isn't
protected for multiple inclusion, and you wouldn't want to override the
SOLIB_ definitions if you're not on AIX.
Hope this helps
