Override -march setting for tegra to -march=armv4t for files that are necessary for low level init on tegra.
The recent change to use -march=armv7-a for armv7 caused a regression on tegra because tegra starts boot on a arm7tdmi processor before transferring control to the cortex-a9. While still executing on the arm7tdmi there are calls to getenv_ulong() and memset() that cause an illegal instruction exception if compiled for armv7.
