Please how to compile Mbrola on Arch Linux Aarch 64

[JanuszChmiel]

I AM visually impaired and I have fall in love with interesting science informatic experiment. The goal of my persoanl experiment is to run Arch Linux on Android device including Orca screen reader support. And because Mbrola voices have better responsiveness and output quality while using it with Pulseaudio, I would like to compile Mbrola for AArch64 on Arch Linux.
But simply typing make do not create binary data.
So do I have to type
make
make install?
I have analysed ArchLinux Aur repository for other platforms but there are no listed dependencies for Mbrola. Who of us would give Me a helping hand?
By The way. Orca run smoothly on Android device thanks to Termux and excellent programmers who are being concentrated aroud Proot for Termux. Really. So if you would give Me some instructions, yours time will not be vasted. I Am patient and I Am ready for informatic science adventures.
The main problem is, if Mbrola do not uses too much shared memory operations. And if it do not require intensive communication with System Bus.
Thank you very much for yours help.

If there's AArch64 support it might also open the doors for Android support with eSpeak NG as frontend.
