Fix: macos compatibility

[OLFDB]

For macos autogen.sh has to be started with --prefix=/opt/local .

There is still an issue with target install-data-hook, but ebusd and tools are working.
I did a quick check building and installing on Debian. That still works, but I didn't test the result.

The VERSION needed to be renamed, as it was generating errors when was imported.

should be fixed with commit to #650 , please check

[john30]

why is this needed?

The MacSDK's termios.h in /Library/Developer/CommandLineTools/SDKs/MacOSX13.3.sdk/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/sys/termios.h shows these definitions at line 316:

#define EXTB    38400
#endif  /* (!_POSIX_C_SOURCE || _DARWIN_C_SOURCE) */


#if !defined(_POSIX_C_SOURCE) || defined(_DARWIN_C_SOURCE)

I assumed the highest baudrate reliably supported is 230400.

AFAIR on Darwin you have to use IOSSIOSPEED to set non-standard speed and it works at least on FTDI for the 921600

Note that all I really want is ebusctl for john30/ebusd-configuration#316 (comment), because I am running ebusd in Docker.

You are missing a library. Use brew install argp-standalone to add it.
