[BZ #1081] * elf/dl-close.c: Include stddef.h. (_dl_close): If called recursively, just remember GC needs to be rerun and decrease l_direct_opencount. Avoid GC if l_direct_opencount decreased to 1. Rerun GC at the end if any destructor unloaded some additional libraries. * elf/Makefile: Add rules to build and run unload6 test. * elf/unload6.c: New test. * elf/unload6mod1.c: New file. * elf/unload6mod2.c: New file. * elf/unload6mod3.c: New file.
