The android build requires that the android/android.toolchain.cmake
toolchain file is used; an error will be raised if ANDROID is defined
without loading the toolchain file.
When targeting ANDROID, the resulting .so files will be placed in
"android/libs/$ANDROID_ABI" even when building out of tree, since it's
where `ant` expects to find them.
Since the Core library is expected to be named 'ppsspp_jni' on ANDROID,
we also put its name in a variable that is set to 'Core' unless building
on ANDROID, where it is 'ppsspp_jni'.
Add missing #include to various files.
strings.h isn't provided by MSVC so we don't include it there; it's needed
for other OSes/compilers.
Get rid of pre-ISO-C malloc.h includes; malloc is provided by stdlib.h.
Fixes some linuxisms.
Prepend __builtin_ to __clear_cache, calling it without the prefix is a
GNU extension.
