Instead, derive -march and -mcpu from the target MCU in target-config.mk. Also (on STM32F4) add the necessary floating point flags. The CodeSourcery toolchains don't support these, so we'll need to prepare alternative toolchains when F4 support is official. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
