Thomas Petazzoni d3539dd53b arch: pass cpu option instead of tune option on ARM ... Currently, the ARM Config.in logic specifies values for --with-arch/-march and --with-tune/-mtune, but not for --with-cpu/-mcpu. However, this causes problems on ARMv4, because specifying --with-arch=armv4t isn't enough to make gcc generate ARMv4 code: one should also pass --with-cpu=<some ARMv4 CPU>. Moreover, since Buildroot is generally designed to generate code specifically for the configured target, it makes sense to give our own --with-cpu/-mcpu value instead of relying on the default value used by gcc, and only do small optimizations with -mtune.
