GNU Arm Embedded ld with LTO support

The current version 7-2018-q2-update of GNU Arm Embedded Toolchain contains arm-none-eabi-ld.bfd, so it does not support Link Time Optimization (LTO).
Is there a problem if I try to compile the LTO version? Is the new linker lto hoping to work? Why wasn't it done? Both versions could be distributed, bfd and lto.

best regards

Max
