sleef: Build fails on Termux / aarch64

Hi, thank you for this library!
I was looking to see if I could use this library for a project, and wanted to check the performance differences on an aarch64 android device I own. For this, I’m using Termux, and encountered the following errors on make. I think it’s related to linking libm, but not sure where exactly the fix goes, or if there is a non-trivial amount of work required to make this work on Termux; will let you know if I find the fix.
See terminal output of `make`.

Hello,
Please check if specifying -DBUILD_TESTS=FALSE as a cmake option works.
