Then something is wrong with your system, this perfectly works for me, 
MINGW_ROOT_PATH is correctly evaluated.

I added this line in toolchain, line 46 to debug :

message(STATUS "cmake root : ${CMAKE_FIND_ROOT_PATH}")

If I run ./configure --cross-compile-win32  (no -DMINGW_ROOT_PATH parameter)
I get :
-- cmake root : /usr/i586-pc-mingw32/sys-root/mingw
  -> default value is used

If I change configure to add -DMINGW_ROOT_PATH=mingw_test
I get :
-- cmake root : /usr/i586-pc-mingw32/sys-root/mingw_test
  -> -D parameter MINGW_ROOT_PATH is correcly used as expected


I use cmake version 2.8.9
