From d4297a13c823b62d29d9850ab5815f6c78baf35a Mon Sep 17 00:00:00 2001

Subject: Use -isystem to include library headers

This way, warnings from headers that come from another package (in
particular linux-headers) won't show up when they get included.

To make sure we still track dependencies, use -MD instead of -MMD.
