+
+	http://gcc.gnu.org/ml/gcc-patches/2008-07/msg01051.html
+
+	to implement Android specific behaviours in gcc, controllable
+	using a single -mandroid option of the arm*-*-eabi* targets.

+
+	- names of startfile and endfile.
+	- list of standard C libraries (libc and, for dynamic
+	  executables, libdl)
+	- name of run-time linker (/system/bin/linker)
+	- Default C option (-fno-excetpions)
+	- Default C++ option (-fno-rtti)
+	- Standand define (__ANDROID__)
+	- Low level linker flags for -shared, -dynamic, -static and -rdynamic.
