[Thomas:
 - Do not make ncurses/readline mandatory dependencies, since they are
   not. They are only needed when building the BIRD client. Added a
   Config.in sub-option to enable/disable the client. As part of this,
   added ncurses/readline to <pkg>_DEPENDENCIES.
 - Add a patch to fix the installation when the BIRD client is
   disabled, the patch has been submitted upstream.
 - Added host-flex and host-bison to <pkg>_DEPENDENCIES since
   flex/bison are used during the build process.
 - Add BR2_USE_MMU dependency, the code uses fork()
 - Fix alphabetic ordering in DEVELOPERS file.]

+Subject: [PATCH] Makefile.in: fix installation with --disable-client
+
+The configure.ac script initializes the CLIENT variable this way:
+
+CLIENT=birdcl
+if client enabled
+ CLIENT=$CLIENT birdc
+fi
+
+This means that checking if @CLIENT@ is empty to decide whether birdc
+should be installed or not doesn't work, and causes a failure at
+installation time when --disable-client is passed.
+
+Instead, check if the birdc binary has been produced or not to decide
+whether it should be installed.
