When code is compiled within the Android tree, the resulting binaries
are intended to run either on the "host" (the machine doing the
building) or the "target" (the machine running the Android operating
system).
"ANDROID" is defined if the code is being compiled for the host or the
target, whereas "__ANDROID__" is only defined for code being compiled for
the target. (yes, I agree, this is not obvious).
gettid() is only declared in the target environment, not the host
environment, so adjust the #ifdef to properly emit the gettid()
definition for binaries targeting the host.
