The change was reverted, so this is currently not necessary.
The next change will discuss remedies.
Again, IMHO, wiki page should be updated (add something like: -z defs
was postponed ... ) and still it should be added a link to
buildflags.md .
BTW "%define _strict_symbol_defs_build 1" will enable -z defs ?
