package/dvb-apps: re-add the patch for gcc < 4.4

The patch 0002-Fix-compiler-warning-flags.patch was
removed when the avr32 architecture was removed.
But it's still needed for blackfin adi-toolchain 2014R1.

+Subject: [PATCH] Fix compiler warning flags
+
+  When building for bfin, the build fails as follows.
+
+  cc1: error: unrecognized command line option "-Wno-packed-bitfield-compat"
+
+An example of an autobuild failure arising from this is the following.
+
+  http://autobuild.buildroot.net/results/92e/92e472004812a3616f62d766a9ea07a997a66e89/
+  http://autobuild.buildroot.net/results/6e7/6e7b48ad9768349d983985c3067c4267cde80541/
+
+Clearly, not all toolchains provide a gcc that understands
+the -Wno-packed-bitfield-compat flag; remove usage of this flag.
+
+Wno-packed-bitfield-compat option was added in gcc 4.4.
+
+[Romain:
+  - This patch is also needed for bfin toolchains which use gcc 4.3.5
+  - Add a link to bfin build failure]
