You could try making similar changes for HAVE_DEVICE_MACROS in the same file (ie. \
disable for android).

You are using...

Linux host
r17b NDK
android-28 platform

I am using...

macOS host
r10e NDK
android-21 platform

In the android-21 version of sysmacros.h the device functions are simple inline \
functions that do a bit of arithmetic. What is in the android-28 version of the file?
