Andoid cross compile: change ANDROID_NDK_HOME to ANDROID_NDK_ROOT

Browse Source 
According to forum discussions with NDK developers, ANDROID_NDK_HOME
is used for something else.

Older versions of the NDK have GCC under their common prebuilt tools directory, so the bin path
will be slightly different. EG: to compile for ICS on ARM with NDK 10d:
export ANDROID_NDK_HOME=/some/where/android-ndk-10d
PATH=$ANDROID_NDK_HOME/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin:$PATH
export ANDROID_NDK_ROOT=/some/where/android-ndk-10d
PATH=$ANDROID_NDK_ROOT/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin:$PATH
./Configure android-arm -D__ANDROID_API__=14

Caveat lector! Earlier OpenSSL versions relied on additional CROSS_SYSROOT
variable set to $ANDROID_NDK_HOME/platforms/android-<api>/arch-<arch> to
variable set to $ANDROID_NDK_ROOT/platforms/android-<api>/arch-<arch> to
appoint headers-n-libraries' location. It's still recognized in order
to facilitate migration from older projects. However, since API level
appears in CROSS_SYSROOT value, passing -D__ANDROID_API__=N can be in

Another option is to create so called "standalone toolchain" tailored
for single specific platform including Android API level, and assign its
location to ANDROID_NDK_HOME. In such case you have to pass matching
location to ANDROID_NDK_ROOT. In such case you have to pass matching
target name to Configure and shouldn't use -D__ANDROID_API__=N. PATH
adjustment becomes simpler, $ANDROID_NDK_HOME/bin:$PATH suffices.
