The following fails when I build binutils with:
configure --build=x86_64-linux --disable-nls --disable-gdb --disable-gdbserver --disable-sim --disable-readline --disable-libdecnumber --enable-obsolete --target=aarch64-linux CFLAGS="-g -O2 -fsanitize=address,undefined -Wno-error" CXXLAGS="-g -O2 -fsanitize=address,undefined -Wno-error" LDFLAGS="-ldl"
Target: aarch64-linux
PASS: aarch64-farcall-b-gsym
Executing on host: sh -c {/dev/shm/e8py6d55/ld/../binutils/objdump  -dr tmpdir/dump > tmpdir/dump.out 2>dump.tmp}  /dev/null  (timeout = 300)

Hi Martin,

  This should be fixed by commit ccf61261eb.
