Title:
  Lack of architecture in gdbstub makes debugging confusing

Status in QEMU:
  Expired

Bug description:
  I spent some quality time debugging GEF and came to a conclusion here:
  https://github.com/hugsy/gef/issues/598#issuecomment-819174169

  tldr;

  * gdb_arch_name was undefined on riscv
  * this bug was fixed recently via 
https://github.com/qemu/qemu/commit/edf647864bdab84ed4b1a4f47ea05be6bb075c69

  
  * An undefined gdb_arch_name results in qemu's gdbstub omitting the 
<architecture> xml.
  * gdb translates a missing <architecture> as "auto" which breaks a lot of 
stuff.
  * tracking down where "auto" comes from is a bit confusing and time consuming.

  
  It might be better to report a missing / blank gdb_arch_name as 
"<architecture>unknown</architecture>" instead of omitting the block completely.
