I noticed that the -use-linker-plugin option seems to be passed to the
linker. This is because LINK_COMMAND_SPEC includes %{u*}. And that
is because -uSYMBOL is a documented linker option.
The effect is that the linker creates an undefined reference to the
symbol "se-linker-plugin". Any user unfortunate enough to link
against a library which contains a definition of that symbol may see
an unexpected result. Admittedly unlikely, but still.
I think we need to fix this option before the release to not overlap
with any existing linker options.
