[Scilab-users] issue building Scilab 6.1.0 arm64 on Ubuntu 19.10 running inside Termux Proot Container

[EnigmaVoidX]

I have been spending a few days compiling Scilab 6.1.0 git on my Ubuntu 19.10
arm64 OS running inside a proot container.  

After patching for the newer jogl2 packages and getting a few more extra
dependencies I have managed to configure and make up to this point:

```
I have installed the latest Valgrind for my distro, version
1:3.15.0-1ubuntu3.1.  

Anyone can enlighten me why it's failing with undefined reference to
vgPlain_tl_pre_clo_init? I can't directly access the valgrind main class
either. My only guess is either my valgrind is to old or new.

I know scilab 6.0.1 works on ubuntu 20 on arm64 so I dont think its an
architecture limitation. Have compiled openfoam, elmerfem, gmsh, getdp,
freecad, paraview and su2 no issues, so what am I missing for scilab?
