[krbdev.mit.edu #2581] AIX shared libraries

[Ken Raeburn via RT]

We're dumping relative paths like "../../lib" into the library search
paths written into the shr.o files.  (Use "dump -Hv" to examine them.)
It should probably be the library install path.  Or possibly we
shouldn't be setting it (by using -bnolibpath).

I'm not sure why, but "../../lib" is confusing gdb when I examine core
files produced by programs three levels down from the top (e.g.,
lib/krb5/krb/t_ser).  It's probably a gdb bug.
