Это намёк на 2 факта:
1. Добавлять %_libdir в LD_LIBRARY_PATH недостаточно, ибо есть ещё /%_lib.
2. Для использования свежесобранной glibc, как правило, использование
свежесобранного же ld.so является необходимым требованием, нарушение
которого грозит SIGSEGV'ами.
Этот факт стоит иметь в виду всем, кто собирает или планирует собирать
glibc.
