gdb-19990121 link failure on rs6000-ibm-aix4.2.0.0

[rodneybrown@pmsc.com]

gdb-19990121 fails to link on rs6000-aix4.2.0.0 with missing externals
for SOLIB_* . These seem to be defines in gdb/{coff-,,som}solib.h
which haven't been setup for this platform.

I note that gdb-19990121 configured and built (this far at least) in a separate
directory from the source. The last time I tried (a few delta's ago) it didn't.
