With no trailing space in LINK_EH_SPEC linker spec gets generated as:
------------------------>8---------------------
%{!r:--build-id} --eh-frame-hdr%{h*} ...
------------------------>8---------------------
or even worse if hash style is added:
------------------------>8---------------------
%{!r:--build-id} --eh-frame-hdr--hash-style=sysv %{h*} ...
------------------------>8---------------------
Now if that spec is really used by LD then it fails inevitably
saying that it doesn't know option "--eh-frame-hdr--hash-style=sysv".
