This change breaks the ability to bootstrap from versions prior to 10.0
because the older lex requires "-ofilename" rather than "-o filename".
Even more annoying, it's not possible to fix it by building the new lex
earlier in bootstrap because the new lex requires a newer m4 be built
first, and building the new m4 requires running this rule which doesn't
work with the old lex.  Grrrr.

It seems like the path of least resistance would be to remove the space
between -o and ${TARGET}, which I'll leave for you if you agree, so that
you can MFC them together when the time comes.
