[PATCH] Create android x86_32 target info

[Tamas Berghammer]

Hi danalbert,

Create android x86_32 target info

On android x86_32 the long double is only 64 bits (compared to 80 bits on linux 
x86_32). This CL creates a new target info class to use the correct size for 
long double on android x86_32.
