[Buildroot] [PATCH] portmap not building static

[ANDY KENNEDY]

Portmap builds and links, however, does not get built correctly when
BR2_PREFER_STATIC_LIB is selected.  There are no dynamic libraries in 
rootfs.tar, however, portmap gets linked dynamically without regards to
the PREFER_STATIC_LIB tags.  LDFLAGS was not being passed into the build of
portmap.  Fixed.
