lld on ubuntu 2304

[masaori335]

In the ci.trafficserver.apache.org/ats/ubuntu:23.04 (ca43c27c309e) image, using lld instead of ld made build failure.

+ /tmp/ats/bin/traffic_server -K -k -R 1
/tmp/ats/bin/traffic_server: error while loading shared libraries: ../src/api/.libs/libtsapi.so: cannot open shared object file: No such file or directory

The libtsapi.so and libtscpputil.so is odd.

...
        ../src/api/.libs/libtsapi.so => not found
        ../src/tscpp/util/.libs/libtscpputil.so => not found

You can reproduce by the ubuntu.pipeline build steps.

This was a problem with the autotools build, where setting LD=lld in config.nice/configure left the libtool-built traffic_server binary referencing the build-tree relative paths ../src/api/.libs/libtsapi.so and ../src/tscpp/util/.libs/libtscpputil.so, which could not be resolved at runtime. The autotools build system (configure, config.nice, all the Makefile.am files, and the libtool .libs handling) was removed entirely in PR #10794, first released in 10.0.0. The project now builds only with CMake, so the configuration that produced this failure no longer exists on master. Closing as obsolete. Please open a new issue if you hit a similar problem with the CMake build.
