Since commit 79d75d752717 (ARM: move -march=* and -mtune= options to arch/arm/Makefile), all the Tegra boards are broken because the SPL is built for ARMv7.

Insert Tegra-specific code to arch/arm/Makefile to set compiler flags for an earlier ARM architecture.

Note: The v1 patch for commit 79d75d752717 *was* correct when it was submitted. Notice it was originally written for multi .config configuration where Kconfig set CONFIG_CPU_V7/CONFIG_CPU_ARM720T for Tegra U-Boot Main/SPL, respectively. But, until it was merged into the mainline, commit e02ee2548afe (kconfig: switch to single .config configuration) had been already applied there.

Changes in v2: - Brush up the commit-description because V1 had a typo (s/look/took/) - Add Jan's Tested-by credit
