I am not sure if that's enough information (it'd be nice to know
the distribution, version of gcc, etc) but I think a workaround
for the problem can be produced.

Isn't the "pentium-m" model the portable/notebook variant? It's
been a long time since I've given much attention to the cpu model

--with-extra-cflags=flags
So you specify
--with-extra-cflags="-mtune=k8 -mcpu=k8"
(or whatever value you want to use).
The values you specify will override the values from cpuinfo.sh
