branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

CLOCK_MONOTONIC_RAW is a fairly recent addition, which may not be
available in old C libraries/kernels. This commit adds a libraw1394
patch that makes the use of CLOCK_MONOTONIC_RAW optional. The patch
has been submitted upstream.

+Subject: [PATCH] testlibraw: build the CLOCK_MONOTONIC_RAW test conditionally
+
+CLOCK_MONOTONIC_RAW is a somewhat recent addition, and some older
+toolchains/kernels may not have the support for it. Therefore, we
+build the part of the test that uses CLOCK_MONOTONIC_RAW only when
+this definition is available.
