Hi,

This patch raises the minimum architectural level for ARM CPUs to ARMv5TE. It is done through changing the -march flag in the current CPU-specific CFLAGS and ASFLAGS.

This patch depends on "Append assembler flags on ARM targets" patch for ASFLAGS handling.

Reason for this change: assembler code in linux_arm_32.s uses PLD instructions. ARM ISA manual mentions this: "This instruction is available in E variants of ARM architecture v5 and above." (thanks to David Holmes for noticing this).

This patch was successfully built here: https://ci.adoptopenjdk.net/view/ev3dev/job/openjdk12_build_ev3_linux/21/

Thanks, Jakub Vanek
