Yikes. I wonder if this is also a problem for ffmpeg:

multilib_src_configure() {

[...]

# LTO support, bug #566282, bug #754654, bug #772854
if [[ ${ABI} != x86 ]] && tc-is-lto; then
        # Respect -flto value, e.g -flto=thin
        local v="$(get-flag flto)"
        [[ -n ${v} ]] && myconf+=( "--enable-lto=${v}" ) || myconf+=(
"--enable-lto" )
fi
filter-lto
