Sometimes it is necessary to give Meson configuration beyond what the eclass currently writes to the .ini files. Multiple native and cross files can be specified, and Meson will use them all. The only rule is that you cannot repeat a section within the same file.
The given argument is used to form the filename for the .ini file. It is important for the filename to be unique because timestamp changes will trigger a reconfigure. meson_append_file uses either --native-file or --cross-file depending on whether we're cross-compiling (including multilib) or not.
