Using add_LDFLAGS should work:

    :program bar {add_LDFLAGS = -L. }{ add_LIBS = -lfoo } : main.c

Putting -L. in add_LIBS will also work.  I'm not sure what is "cleaner".

Another mechanism is to refer to the library directly instead of with
"-l":

    :program bar { add_LIBS = $(DLLPRE)foo$DLLSUF } : main.c

That can also be used when the library is in another directory or
produced by a child recipe.
