dev-qt/qtdeclarative-5.5.0 in the Qt overlay wants to patch out JIT support if USE="-jit" is specified: src_prepare() { use jit || epatch "${FILESDIR}"/${PN}-5.4.2-disable-jit.patch It looks like it's used in all versions of the ebuild in the Qt overlay: qtdeclarative # grep disable-jit *.ebuild qtdeclarative-5.5.0.ebuild: use jit || epatch "${FILESDIR}"/${PN}-5.4.2-disable-jit.patch qtdeclarative-5.5.9999.ebuild: use jit || epatch "${FILESDIR}"/${PN}-5.4.2-disable-jit.patch qtdeclarative-5.6.9999.ebuild: use jit || epatch "${FILESDIR}"/${PN}-5.4.2-disable-jit.patch qtdeclarative-5.9999.ebuild: use jit || epatch "${FILESDIR}"/${PN}-5.4.2-disable-jit.patch But that file doesn't exist in the overlay (it does in the main Portage tree, but that doesn't help).

Copying qtdeclarative-5.4.2-disable-jit.patch from the main Portage tree into the Qt overlay makes it build, but I'm not sure how to test if it works. By the way, I'm hitting this because USE="-jit" is default for Hardened.
Thanks, fixed in git. https://gitweb.gentoo.org/proj/qt.git/commit/?id=07529d2a4ce81d8a3b6273a5ed6e39e15cd88fe9
