ARM: Fix clone build for ARMv4
ARMv4 does not have the blx instruction, so use the BLX macro which handles abstracting this for us. Build tested for armv7, armv4t and armv4. ports/ChangeLog.arm: 2014-01-24 Will Newton <will.newton@linaro.org> [BZ #16499] * sysdeps/unix/sysv/linux/arm/clone.S: Use BLX macro instead of blx instruction directly.
