No, I wouldn't recommend a user mode qemu for gdb work.  A system mode
qemu does work for building and running gdb.  I used this to develop
the risc-v linux native gdb port.  Though I suspect trying to run the
gdb testsuite on qemu would find some interesting risc-v qemu bugs.
It is possible to use a cross gdb with a program running on a system
or user mode qemu via target remote, though I don't test this very
often.
