x86-32 will be the lowest common settings for all 32bit cpus.
so pentium4 is the setting I believe you should use.
I can tell you from my experience, since I use PentiumD cpu, that
recompiling with -march=prescott gave me better performance then
-marh=x86-32, especially in disk intensive and multimedia applications, such
as video encoding and large database access.
