There seems to be plenty of precedent for --argument=value in GNU ld,
but the documentation says:

       Arguments  to  multiple-letter  options  must  either  be
       separated from the option name by an equals sign, or be given as
       separate arguments immediately following the option that
       requires them.  For example, --trace-symbol foo and
       --trace-symbol=foo are equivalent.  Unique abbreviations of
       the names of multiple-letter options are accepted.

I always use the space, personally, so I'd be pretty confused by the
dummy option handling; how about supporting that too?

I'm somewhat surprised the hack is necessary, but I'm sure you're right
:-)

As a first cut to fix the configury option, we could always enable
sysroots for native tools.  Right now the differences in linker script
generation are only the addition of the '=' marker, the use of
NATIVE_LIB_DIRS (already enabled for natives), and something
complicated for $(tooldir) that I can't quite remember the purpose
of...
