The same error also happen with Android NDK (clang cross compiler). The following patch may work.

@Biswa96 thanks for the pointer, going to try it now.

I am not sure if the patch is correct or not. axel maintainer told that the patch is not appropriate https://github.com/termux/termux-packages/issues/19093
