The distributions are the least trouble. If sane, they have a global configuration file that specifies various options, including C flags. E.g. I have all configurations set up in ~/.rpmrc and it currently includes appropriate flags for "alpha", "i386", "i486", "i586", "i686" and "mipsel". Depending on which of these CPUs I select when building a package, the toolchain receives appropriate flags. Of course, a package built for "i686" might not necessarily run on an i386 CPU (and at least one distribution I know of makes an active use of this property). Since my "mipsel" configuration has to run on an R3400 chip, it only specifies "-pipe -O2 -fomit-frame-pointer", but if I needed an entry for a better MIPS CPU entry I would simply add it. -- + Maciej W.
