Use __ANDROID__ to prepare for upcoming arm_linux_androideabi toolchain.

This patch does not affect current arm-eabi toolchain behavior at all.
It only makes arm_linux_androideabi toolchain to do the same as arm-eabi does.

The current arm_eabi toolchain does not define __unix nor __unix__, so
some statements wrapped by "#if defined (__unix) || defined (__unix__)"
"#endif" won't be included. However, the new arm_linux_androideabi
targets a linux Android platform, where __unix and __unix__ are
defined, which results in the incorrectly inclusion of calls of
IsNANorINF, IsINF, IsNegNAN, ecvt_r, fcvt_r, etc. We need to add
__ANDROID__ to prevent these calls from being included.

As a background, arm_linux_androideabi will be supported by upstream gcc
trunk soon. __ANDROID__ is defined by arm_linux_androideabi toolchain.
