--- Comment #3 from Timo Teräs <timo.teras at iki dot fi> --- (In reply to Andrew Pinski from comment #2) > Are we sure this is not a musl issue? Same source code / out-of-tree bootstrap in musl environment works for triplets: armhf-alpine-linux-muslgnueabihf i586-alpine-linux-musl x86_64-alpine-linux-musl But it is possible there's something in musl aarch64 specific headers, or in the build process that triggers only in musl/busybox environment. For example, it could be also some sed/awk script that depends on GNU extensions, or even busybox bug. I'll try to compare in-tree and out-of-tree builds see if I can pinpoint this to something specific.
