ln: illegal option -- T on macOS Catalina

I encountered the following error on macOS Catalina:

Setting GHC to 8.6.5
ln: illegal option -- T
usage: ln [-Ffhinsv] source_file [target_file]
       ln [-Ffhinsv] source_file ... target_dir
       link source_file target_file
"ghcup set" failed!

Seems like the ln command does not support -T option.
