Option to install GCC 11

[MartinXPN]

Thanks for the provided sample for installing gcc on an aws lambda machine.
I was wondering if there is any way of installing a later version of gcc? 7.3.1 is a bit outdated already and would be really helpful to install versions like 11.2 or 10.3. Is there any way of doing it cause I think lambci/yumda:2 does not support binaries for versions other than 7.3.

Any kind of help or direction would be really great!
