Bump cross-arm-none-eabi gcc and binutils to match non-cross packages
https://github.com/void-linux/void-packages/pull/37580

Description:

#### Testing the changes
- I tested the changes in this PR: YES
I tested this with my own personal armv7 projects.  Notably, the version currently in packages has a bug with LTO that makes it discard ISR functions/symbols inappropriately, making LTO useless for some embedded use cases.  This appears fixed in gcc 10.

#### Local build testing
- I built this PR locally for my native architecture, amd64/glibc
