This code is about invoking system default SIGABRT action which is usually to
dump a core. Calling abort() is simple enough it IMO does not make sense to
move it to some host/target-dependent file.
You are probably suggesting that GDB could fork, attaching to its copy (in
a new inferior) and invoke gcore on the copy. This would be a functionality
enabled only for native targets (*-nat.c) so that it could dump core even on
operating systems not supporting such operation.
It would be a feature currently unsupported by GDB and out of the scope of
this patch. Still the system core dumping would be preferred over this
GDB-native dump as it is more safe for half-crashed GDB. Therefore such
functionality would have limited audience.
