How about changing the description to: The format is `property-name=<value>` with no space around the +=+ sign, and with single quotes around string values. ? Regards, John

With autoconf packages, we often specify ac_cv_func_... cached values to avoid runtime checks during configure. With meson the equivalent is setting properties in cross-compilation.conf which we cannot do in Buildroot at the moment. For example, libglib2 used to set ac_cv_func_printf_unix98 and ac_cv_func_vsnprintf_c99 so that the system printf could be used, but with the conversion to meson these checks fail and the gnulib fallback is used. Add infrastructure in the same way as FOO_MESON_EXTRA_BINARIES to allow per-package modification to the cross-compilation properties.
