+ * on shared libraries). It is called from arch-$ARCH/bionic/crtbegin_static.S
+ * which is directly invoked by the kernel when the program is launched.
+ *
+ * The 'structors' parameter contains pointers to various initializer
+ * arrays that must be run before the program's 'main' routine is launched.
