Please have a look at:

https://lists.rtems.org/pipermail/devel/2019-December/056517.html

I was able to build it on Debian 10:

Checking for library LLVM                : yes
Checking for header llvm/DebugInfo/Symbolize/Symbolize.h : yes
Checking for library ws2_32                              : not found

sh at gcc68:~/rtems-tools$ ./build/trace/rtems-record-lttng --help
./build/trace/rtems-record-lttng [--host=HOST] [--port=PORT] 
[--limit=LIMIT] [--elf=ELF] [INPUT-FILE]

Mandatory arguments to long options are mandatory for short options too.
   -h, --help                 print this help text
   -H, --host=HOST            the host IPv4 address of the record server
   -p, --port=PORT            the TCP port of the record server
   -l, --limit=LIMIT          limit in bytes to process
   -e, --elf=ELF              the ELF executable file
   INPUT-FILE                 the input file
