No, not built-in. However it's very easy to use qemu in conjunction with 
the -S and -s command line options to attach a cross-gdb to your virtual 
machine. In fact, using this approach in conjunction with the unstripped 
OpenBIOS image makes it possible to insert breakpoints into the C 
sections of OpenBIOS and step through as required.

See my post from the archives here:

for more detail on how I managed it for SPARC64.


HTH,

Mark.
