termux-ubuntu on Galaxy A10 64bit runs only on 32 bit

[ronnac]

Note: I also opened an issue in termux app github.
I installed termux-ubuntu on a Samsung Galaxy A10 which has an armhf 64bit architecture (Exynos 7884).
However the command
"getconf LONG_BIT" yields 32, meaning termux-ubuntu uses 32bit. The underlying termux also uses 32, which might be why. I wanted to be sure that the termux-ubuntu install script properly detects armhf 64bit.
