Material Maker 1.5 Linux doesn't launch on Ubuntu 22.04

[cmontesano]

Material Maker version:
1.5

OS/device including version:
Ubuntu 22.04

Issue description:
I get the following errors upon launch:

$ ./material_maker.x86_64 
./material_maker.x86_64: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.38' not found (required by ./material_maker.x86_64)
./material_maker.x86_64: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.36' not found (required by ./material_maker.x86_64)
./material_maker.x86_64: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.38' not found (required by ./material_maker.x86_64)

Ubuntu 22.04 ships with glibc 2.35, and is still LTS until June 2027.

Replacing the custom export template with the official template works to launch the program, but I'm wary of potential side effect that may manifest as a result of not using the custom build.

Steps to reproduce:
Launch material_maker.x86_64 on a system with a glibc older than 2.38.

but I'm wary of potential side effect that may manifest as a result of not using the custom build.

Everything should work the same, except exporting to .exr won't work as this is what requires a custom build.
