I imagine that the supported gcc version will be that provided by the 
distributions being offered. For Debian, you can find out versions by 
searching on the packages site:

https://www.debian.org/distrib/packages

Searching for "gcc" should provide results that employ descriptive package 
versions corresponding to the actual gcc version involved in each case 
(although you may need to strip off prefixes like "4:" and suffixes like "-1" 
as in "4:6.1.1-1" to get "6.1.1").

I see gcc 6.2.0 on Debian unstable, myself, but that's on i386. Nevertheless, 
the supported architectures tend to offer the same versions of things if at 
all possible. My cross-compilers seem to be 5.4.0, but an update is apparently 
pending with those.

I can't answer the specific questions about the A20, but maybe the gcc ARM-
related notes can provide some answers. For example:
