set_gdbarch_iterate_over_regset_sections() is used to add coredump support.

However, in most examples found in the code base, we look for a
section called ".reg", which fails with "Couldn't find general-purpose
registers in core file." if such a section could not be found.

In our port, Linux stores coredump registers in NT_PRSTATUS of the core file.

How does one get GDB to use core file NT_PRSTATUS instead of section
".reg" to retrieve general-purpose registers ?
