Warning in logfile with use of Arduino toolchain

Uploading an Arduino sketch also shows a warning in the log file.

Warning: platform.txt from core ‘SODAQ SAMD (32-bits ARM Cortex-M0+) Boards’ contains deprecated recipe.ar.pattern="{compiler.path}{compiler.ar.cmd}" {compiler.ar.flags} {compiler.ar.extra_flags} “{build.path}/{archive_file}” “{object_file}”, automatically converted to recipe.ar.pattern="{compiler.path}{compiler.ar.cmd}" {compiler.ar.flags} {compiler.ar.extra_flags} “{archive_file_path}” “{object_file}”. Consider upgrading this core.

Can this be ignored?

Yes, this can be ignored.

It is complaining about a specific line in platforms.txt is using an old style specification.

This warning used to show when compiling for the Arduino Zero as well. However, they seem to have updated it now.
