ARM Support

[LuPoMicron]

Hi,

It would be very easy to add also ARM support to your Makefile.
I tested with the following changes and it works on Android.

Cheers,
Luca

Thanks very much! I tested it once on an ARM but I didn't document the compiler flags I used.

Since ARM targets are so varied, I'd prefer to not clutter up the Makefile with arch-specific settings. Can you please:

• Paste in a make command that works for your system? I'm guessing from your patch it would be something like so:

    make CC=arm-linux-gnueabi-gcc CFLAGS='-Wall -O2 -std=c99 -fomit-frame-pointer -D__USE_STRING_INLINES -pipe -static -s'
    

• Some specifics about your target, and any insights into why these compiler options were required. Just whatever info you have on-hand and don't mind revealing is fine -- it might be useful to people porting to other systems.

I'll add your information to the PORTABILITY section in the docs (or possibly make a new PORTING.md file in the repo).

Thanks!
