srv-shared build stuck at building CV8/ICU4U

[ChunbleBee]

Using the given makefile for srv-shared, I cannot seem to build past CV8, in particular the ICU4C submodule, on the node/server, despite my best efforts. I seem to be able to build the submodule directly (cding into the directory, then make), but it fails when trying to build from the srv-shared makefile. Make keeps giving me an error that the C Compiler doesn't work, but I've tested gcc and clang with multiple other projects, and it seems to work fine, not to mention that all the other submodules seem to build without issue as well.

Device information:

• Device: Microsoft Surface 3 (Intel Atom x7-8700, 2GB RAM)
• OS: Ubuntu 20.10
• Repo Version: Most Current
• Pretty much every up-to-date C-Compiler available in Apt installed, with Multilib

clang: error: invalid linker name in argument '-fuse-ld=lld'

You need to install lld. If you look in env/setup-lnx.sh you can see all the things our GitHub Ubuntu 20.04 CI installs to make the build work (which includes lld).
