gcc 12 and later generate a mainly useless linker warning:

warning: <TARGET>.elf has a LOAD segment with RWX permissions

For the SITL, ex-MacOS, suppress this.

Tested on:

  • Arch Linux (gcc 13.1.1)
  • FreeBSD (gcc 13.0.1)
  • Cygwin (gcc 11.3)
  • MacOS (clang)

Note: If it is ever possible to build reliable firmware with cmake and gcc 12 or later, the same directive may be applied to firmware builds.

Well, well gcc, 11.3 / Cygwin works, 11.3 Linux doesn't.
