Hello, I found a typo in ebuild mentioned in summary. It is in a src_configure() function: $(use_enable threads thread_safety) but should be: $(use_enable threads thread-safety).
it still works because of how configure parses options -- it internally normalizes the - to _
should be all set now in the tree; thanks for the report! Commit message: The thread option uses a - separator http://sources.gentoo.org/dev-libs/elfutils/elfutils-0.154-r1.ebuild?r1=1.1&r2=1.2
