Buildroot commit dcee99507c6767230fd1faeeefe95f5662eb03a3 bumped icu from
version 73-2 to 77-1.

Upstream raised the minimum C++ requirement to C++17 in version 75-1:

https://github.com/unicode-org/icu/releases/tag/release-75-1
https://icu.unicode.org/download/75
"C++ code now requires C++17 [...]"

This commit switches the minimum gcc version to 7.

No autobuilder errors were recorded which relate to the gcc version used.

Thanks, I did test and indeed the build fails with gcc 6.x, but works
with gcc 7.x, so I've applied, but I had to make quite a few additional
tweaks:
