Normally you would use output/staging/usr/bin/$PREFIX-gdb, but OK.

Don't add lib at the end. solib-absolute-prefix is a PREFIX, not the
location of the library files.

Again, please point gdb at the unstripped version in
output/build/openssh*/ssh-keygen instead of the (potentially) stripped
version in target.

Sorry. don't know. I've never uses the SSP stuff.

Rebuild is controlled by the .stamp_* files inside build/openssl*/, so
it only gets rebuilt if you remove those (or remove the entire openssl
dir). Notice that dependent packages don't get rebuilt automatically.
