Add the OpenWrt TARGET_LDFLAGS to the compile command to activate PIE support
for the io tool when it is activated globally in OpenWrt.

On 64 bit Linux systems long is 8 bytes long, on 32 bit Linux systems it
is 4 bytes long. Here we want to print 4 bytes and not 8 bytes, use int
instead of long.
This fixes printing 4 bytes on 64 bit systems.

Only when /dev/mem is opened with O_SYNC the write and *read* is done
uncached. We saw wrong values read out from the hardware without setting
O_SYNC, the busybox devmem tool showed different values, when O_SYNC is
also set for the io tool, it reads out the same values as devmem.
When looking at the drivers/char/mem.c file in the kernel it is behaving
differently based on the O_DSYNC flag.
