Partial fix for bug 2758 - Android issues with NDK r10c and API-21

Sylvain

When using API 21 and running on an old device (android < 5.0 ?) some function are missing.

functions are (at least) : signal, sigemptyset, atof, stpcpy (strcat and strcpy), srand, rand.


Very few modifications on SDL to get this working :

on SDL
======

Undefine android configuration :

HAVE_SIGNAL
HAVE_SIGACTION
HAVE_ATOF

In "SDL_systrhead.c", comment out the few block of lines with "sigemptyset".

Android.mk:
remove the compilation of "test" directory because it contains a few rand/srand calls

Also, there are more discussions about this in internet :
