+Remove __assert_fail()
+
+The netplug code uses the assert() macro in various places. In glibc
+internally, assert() uses a function called __assert_fail() to print a
+message and abort. Relying on internal glibc details, netplug
+re-defines __assert_fail() in the hope that it will get called instead
+of glibc internal version.
+
+This attempt:
+
+ * Doesn't work with uClibc, which doesn't use any __assert_fail()
+   function at all. It doesn't fail to build, but it is entirely
+   useless.
+
+ * Fails to build with musl, which also defines __assert_fail(), but
+   with a different prototype.
+
+We simply remove the __assert_fail() implementation, so that the C
+library implementation of assert() just does its normal work. The only
+functionality lost is that the message is displayed on the standard
+output rather than in netplug's logs (and this was only working with
+glibc anyway).
