Thanks for doing this!

Better put this into the toolchain/Makefile.in, like:
+ifeq ($(BR2_PREFER_STATIC_LIB),y)
+BR2_SHARED_LIBS:=--enable-static --disable-shared
+else
+BR2_SHARED_LIBS:=--disable-static --enable-shared
+endif
and use ./configure $(BR2_SHARED_LIBS) ...

This can't be right.

Shouldn't this libintel rather go into HOST_LOADLIBES for windows?
