While our Linux bots have been happy with the changes, I’m not familiar with the build configurations involving the build-your-own-ICU path, nor with FreeBSD, Cygwin, Android, etc. I would like to make sure that all supported configurations still work, can someone help me with this?

In this configuration, user programs that link against the static library should also be told explicitly to link against ICU (e.g. “-licu*”). On Darwin, the least evil approach was autolinking by emitting a linker option via inline asm in the shims library. Is there an approach that would work for Linux? An alternative solution could be adding the flags in the Swift driver itself, but that would mean that any build systems that bypass the Swift driver would also need to be updated to pass those same flags.
I tried this one but I'm afraid the support for FreeBSD bitrot enough
that I didn't even get to the point where this failed.
I have a crash in the compiler/verifier instead.
Please let me know if you need other infos.
