+Subject: meson: Fix cross-building of dtrace probes
+MIME-Version: 1.0
+Content-Type: text/plain; charset="utf-8"
+Content-Transfer-Encoding: 8bit
+
+dtrace invokes the C compiler, so when cross-building we need
+to make sure that $CC is set in the environment and that it
+points to the cross-compiler rather than the native one.
+
+Until https://github.com/mesonbuild/meson/issues/266
+is addressed, the workaround is to call dtrace via env(1).
