package/dvblast: fix static linking
dvblast links to -lev, which calls functions from -lm, like floor().
dvblast does not use libtool, so it does not pull in the libev
dependencies when doing a static link.
Fix that by always pulling in -lm after -lev. We can not do it from the
.mk, because libraries passed from the .mk end up at the beginning of
the list.
