Disable SSE3 routines in glibc

[Thawan Kooburat]

Hi,

Because of my work, I need to prevent glibc from using SSE3 routine
such as __strncpy_ssse3 even though the machine supports those
features.

My current solution is to recompile glibc from source rpm.  However, I
am not sure if there is a flag that I add into the spec to do what I
want.

There seems to be --host option of 32-bit that allow me to target
specific CPU (i[345]86) but I don't see if there is a similar option
for x86_64 machine.

Any suggestion?
