--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to etienne_lorrain from comment #3) > Unlike for ARM64 host compiling a native compiler, you need to say such > --disable-multilib for amd64 compiling a native compiler. Well aarch64 (arm64 [which is techincally not a thing]) defaults to having only one multi-lib (LP64) while x86_64 (amd64 which is the non-canonical name for x86_64) defaults to having both 64 and 32bit multi-lib.
