100% tested. Assuming that you don't need to test an obvious change,
because it only changes one line is dangerous. I will learn from this,
sorry for the inconvenience.
`gcc-armhf` compiles fine again with that change, and it is able to
cross-compile packages as it used to.
* gcc-armhf: has been updated upstream (minor code change without version bump)
* musl-armhf: use default mirror from config instead of random other https mirror
Rebuilding the packages is not required.
