undefined reference to debuginfod_get_url and debuginfod_set_progressfn while linking perfparser

The compilation of hotspot 1.5.1 fails with

The two symbols are exported in libdebuginfod.so, but this library is not provided to the linker. Also, neither libdw nor libelf link to it on my build.

At the start of the compilation, I noticed the following:

 * SED: the following did not cause any changes
 *     sed -i '/target_compile_definitions(libhotspot-perfparser PRIVATE HAVE_DWFL_GET_DEBUGINFOD_CLIENT=1)/d' 3rdparty/perfparser.cmake || die "sed failed for perfparser";
 * no-op: -e /target_compile_definitions(libhotspot-perfparser PRIVATE HAVE_DWFL_GET_DEBUGINFOD_CLIENT=1)/d
 * Source directory (CMAKE_USE_DIR): "/dev/shm/portage/dev-util/hotspot-1.5.1/work/hotspot"
 * Build directory  (BUILD_DIR):     "/dev/shm/portage/dev-util/hotspot-1.5.1/work/hotspot_build"
 * Hardcoded definition(s) removed in tests/test-clients/CMakeLists.txt:
 *  set(CMAKE_BUILD_TYPE RelWithDebInfo)
>>> Source prepared.
>>> Configuring source in /dev/shm/portage/dev-util/hotspot-1.5.1/work/hotspot ...
 * Source directory (CMAKE_USE_DIR): "/dev/shm/portage/dev-util/hotspot-1.5.1/work/hotspot"
 * Build directory  (BUILD_DIR):     "/dev/shm/portage/dev-util/hotspot-1.5.1/work/hotspot_build"

and one can see that HAVE_DWFL_GET_DEBUGINFOD_CLIENT is set to 1.
