* Do not use _GNU_SOURCE gratuitously. What is needed to build whisper.cpp and examples is availability of stuff defined in The Open Group Base Specifications Issue 6 (https://pubs.opengroup.org/onlinepubs/009695399/) known also as Single Unix Specification v3 (SUSv3) or POSIX.1-2001 + XSI extensions, plus some stuff from BSD that is not specified in POSIX.1. Well, that was true until NUMA support was added recently in ggml, so enable GNU libc extensions for Linux builds to cover that. There is no need to penalize musl libc which simply follows standards. Not having feature test macros in source code gives greater flexibility to those wanting to reuse it in 3rd party app, as they can build it with minimal FTM (_XOPEN_SOURCE=600) or other FTM depending on their needs. It builds without issues in Alpine (musl libc), Ubuntu (glibc), MSYS2. * examples : include SDL headers before other headers Avoid macOS build error when _DARWIN_C_SOURCE is not defined, brought by SDL2 relying on Darwin extension memset_pattern4/8/16 (from string.h). * make : enable BSD extensions for DragonFlyBSD to expose RLIMIT_MEMLOCK * make : use BSD-specific FTMs to enable alloca on BSDs * make : fix OpenBSD build by exposing newer POSIX definitions * cmake : follow recent FTM improvements from Makefile |

command
This is a basic Voice Assistant example that accepts voice commands from the microphone. More info is available in issue #171.
# Run with default arguments and small model
./command -m ./models/ggml-small.en.bin -t 8
# On Raspberry Pi, use tiny or base models + "-ac 768" for better performance
./command -m ./models/ggml-tiny.en.bin -ac 768 -t 3 -c 0

Guided mode
"Guided mode" allows you to specify a list of commands (i.e. strings) and the transcription will be guided to classify your command into one from the list. This can be useful in situations where a device is listening only for a small subset of commands.
Initial tests show that this approach might be extremely efficient in terms of performance, since it integrates very well with the "partial Encoder" idea from #137.
# Run in guided mode, the list of allowed commands is in commands.txt
./command -m ./models/ggml-base.en.bin -cmd ./examples/command/commands.txt
# On Raspberry Pi, in guided mode you can use "-ac 128" for extra performance
./command -m ./models/ggml-tiny.en.bin -cmd ./examples/command/commands.txt -ac 128 -t 3 -c 0

Building
The command tool depends on SDL2 library to capture audio from the microphone. You can build it like this:
# Install SDL2 on Linux
sudo apt-get install libsdl2-dev
# Install SDL2 on Mac OS
brew install sdl2
make command
