Unauthorized sincos during LAPACK build

Following the instructions here I created the Fortran NDK toolchain binding (OSX, NDK-7b) with the goal of creating a LAPACK / BLAS.

Using android-cmake with source 3.4.0 net lib seems to me almost successful. However, the BLAS assembly fails when one of the tests is bound (with an error indicating unresolved sincosand sincosf). A small search shows that these features are not available in older versions of Android. I am wondering what is the best way to solve these features?

The following is an example of a connection error:
