Comment 1 for bug 662720

Specifying both -march= and -mcpu= is redundant, and may not in fact have done what you expected in previous compiler versions (maybe even depending on the order in which the arguments were given). The -march switch selects a "generic" ARMv7-A CPU, and -mcpu selects specifically a Cortex-A8 CPU with tuning specific for that core.

Either use "-march=armv7-a -mtune=cortex-a8", or just use "-mcpu=cortex-a8".
