Summary

fix ptest for gperftools by adding runtime library path in %check.

Root Cause:

• Test binaries cannot load freshly built shared libs during %check: error while loading shared libraries: libtcmalloc*.so / libprofiler.so: cannot open shared object file

Fix Implemented:

• The tests execute binaries from the build tree (including .libs/lt-* wrappers).
• Those binaries need the just-built libs in .libs before install.
• Without LD_LIBRARY_PATH, dynamic loader cannot find them, leading to widespread exit 127.
