[Bug gdb/10743] Process record doesn't support instruction 0xf6e

I have exactly the same problem on ubuntu 9.04 x86_64 with glibc 2.9-4ubuntu6.1
but with memset.

To overcome this, I do the following in gdb before starting target record, to
work around:

set __x86_64_preferred_memory_instruction=0

Following memset.S (and cacheinfo.c), this will force memset to use 'regular
instruction' instead of SSE - and it allows me to reverse debug :-)

Not sure this is honored in glibc 2.10 for strrchr but you could give a shoot.
