Subject: [PATCH] rtmpdump: fix cross with Clang
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

"clang" is not the correct value for CC when cross compiling — it
should be the prefixed, wrapped clang for the host platform.  Let's
force the use of our original CC in all cases.
