Moarvm seems quite special as no other\npackages need host-luajit but no luajit on the target.\n\nLooking at the upstream project, it doesn't seem to explicitly need\nhost-luajit, just host-lua would do. From Configure.pl:\n\n=item --lua=path/to/lua/executable\nPath to a lua executable. (Used during the build when JIT is enabled).\n\nThis configure option is even dropped in 2017.10 with the following\ninformation in the changelog:\n\n+ Removal of Configure.pl --lua and --has-dynasm options, compiling with these\nincluded 3rdparty libs is now required\n\nWhere the embedded lua copy is a tweaked lua-5.1.5:\n\nhttps://github.com/MoarVM/dynasm/blob/d84e11714c9460bbb032de6cb1e06c3cb1c31f07/minilua.c\n\nAnd indeed, moarvm still builds if moarvm.mk is changed to pull in\nhost-lua and the --lua path is adjusted. Francois, is there a specific\nreason you went with host-luajit over host-lua?\n\nSo I would prefer to do that change instead of adding\nBR2_PACKAGE_HOST_LUAJIT_ARCH_SUPPORTS.\n\nI'll send a patch for moarvm.","headers":{"Return-Path":"","X-Original-To":["incoming@patchwork.ozlabs.org","buildroot@lists.busybox.net"],"Delivered-To":["patchwork-incoming@bilbo.ozlabs.org","buildroot@osuosl.org"],"Authentication-Results":["ozlabs.org;\n\tspf=pass (mailfrom) smtp.mailfrom=busybox.net\n\t(client-ip=140.211.166.133;
