signedness issue on ARM platform

By default ARM processors typically use unsigned char for char type. That why signed char use must be forced.
I used arm-linux-gcc-4.2.1 compiler.

Submitting patch for this problem to solve:

Specify the sources and various flags for the iperf binary

iperf3_SOURCES = main.c
-iperf3_CFLAGS = -g -Wall
+iperf3_CFLAGS = -g -Wall -funsigned-char

Tested with:
arm-linux-gcc-4.2.1
mipsel-linux-gcc-4.1.2

Just fixed one case of signed/unsigned char problem, with getopt_long. Not enough info in this problem description to know if there are other instances.

Found & fixed another signed/unsigned char problem. That's probably all.

Status: Fixed
