workaround.

That option disables the "qSearch:memory" remote serial protocol packet.  I.e.,
when the option is on, GDB sends the pattern to GDBserver, GDBserver does the
searching, and returns back the result to GDB.  When the option is off, GDB
falls back to search memory itself, by reading memory blocks out of the remote
target's memory.  The latter is much slower.  "qSearch:memory" is thus an
optimization.

Look for qSearch:memory at:
