Fixes for icu 77 should be available upstream or at Fedora/Gentoo/LFS. Icu 78 is fresh ;)

notes for future rebuilds:
1. rebuild libxml2 with icu disabled to staging
2. update icu to staging
3. rebuild libxml2 with icu enabled ("pkgctl build -c --staging --offload")

later there's a chain:
haskell-*
haskell-pandoc*
pandoc-cli
pandoc-crossref
pandof-plot
nuspell
gspell

cuda-tools comes from a binary source, there is nothing to rebuild

Packages go to staging
