Just to make sure:
With the toolchain in question, the headers and the actual 
library didn't agree whether sincos() is available or not.
Maybe I am too harsh, but I still believe this defines a 
broken toolchain. A simple workaround was found.
If this is really the typical situation when building for 
Android, we can add the check to configure (so that the 
workaround would not be necessary) but fate builds for 
Android and this problem was only reported once so I 
assumed a local breakage / a broken installation.

The relevant issue here (on this mailing list) is - as the 
link above shows - that only unpatched current FFmpeg is 
supported here and that I (still) believe it allows to 
build for Android.
