Merge bitcoin/bitcoin#22365: guix: Avoid relying on newer symbols by rebasing our cross toolchains on older glibcs
647f7e5f1da1089d451f3c431efc635b8e87b064 guix: Also sort SHA256SUMS.part (Carl Dong)
dc4137a60c99979b89f75d2bddba96d043f387b8 guix: Build depends/qt with our platform definition (Carl Dong)
16b0a936e15b81710755303e11ef51f608b61475 guix: Rebase toolchain on glibc 2.24 (2.27 for riscv64) (Carl Dong)
Pull request description:
After this PR, we'll have the following:
- riscv64 -> build with a toolchain targeting glibc 2.27
- everything else -> builds with a toolchain targeting glibc 2.24, but will not have symbols > 2.17 (checked by `symbol-check.py`)
