Hello everyone,

Here are some minor changes I'd like to propose to flag-o-matic's
_filter-var() to work properly with LDFLAGS.
Without this, things like "-Wl,-O1,--as-needed" won't be affected by any
kind of filter since there are no spaces to separate each flag.

I don't know of any better way to do this, but here's a patch that works
just fine.

Regards,
Tomas
