While I find the disregard for standard compliance in Android deeply 
disturbing, in this case the right fix is to remove npth_yield entirely 
(which should have been a function anyway, as it needs to release the 
global lock temporarily).  yield is considered harmful, and I changed 
the only place where it is called in gnupg with a sleep (well, there are 
some more calls in the windows CE port which will eventually be taken 
care of).

npth: c30634abebb287f56a6a2480b4bbd2ffc166dd4d
gnupg: 8f8c6594147608b1021c16fc3561feb96da5d55a
