archive_test.ww absorbs 610_arch and 632_w6l_manyflags: archive
member selectivity through a load-bearing undefined @symbol extern
(link exit 0, run exit 7), and the -L capacity table {1,64,65,100,
128} against both w6l and w6l_ww with an ET_EXEC check per leg. ar is
/usr/bin/ar via runcommand; the junk -L flags are real argv entries
instead of a 16KB shell string.
link_test.ww absorbs 600_w6l and 620_data_link: ET_EXEC on the
trivial pipeline, writable-global read/write runs, the exact
two-PT_LOAD R+X/R+W split, the single-PT_LOAD no-DATAW invariant 992
depends on, and the BSS filesz trim (filesz 1 < memsz 32, loader
zero-fill). Strengthened: the ldd staticness proxy is replaced by a
direct no-PT_INTERP phdr scan.
elfobj_test.ww (test/object, on testenv) absorbs 500_w6a, 510_dataw,
and 520_datar: ELF64 header magic/class over the 4 inline programs,
DATAW section/symbol layout plus the 6-section no-DATAW legacy
invariant 991 depends on, and the DATAR .rela.data reloc through
link and run. Strengthened: the reloc symbol is resolved to
'greeting' (declared but never implemented in the C carrier).
