commit: https://git.buildroot.net/buildroot/commit/?id=cf865e061e38f1a32ae5c2d47e10c00441f33c4e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Drop sha256 hash. The combination of md5 and sha1 hashes is enough.

Add a patch that fixes a build failure due to using the compiler of the
host machine. The patch has been submitted as a pull request:

+Subject: [PATCH] doc/examples/Makefile.am: define C and C++ compilers for
+ CMake
+
+This prevents build failures when cross-compiling.
+
+If we don't define the compiler, it will use the one from the host
+machine. For instance "/usr/bin/c++", which is incorrect.
+
+The failure looks like this:
