Summary:                    Multiple redefinitions with cross compilation for
eCos
Description: 
Using the following sequence to enable eCos cross-compilation (from any host):

INCLUDE (CMakeForceCompiler)
SET (CMAKE_SYSTEM_NAME eCos)
CMAKE_FORCE_C_COMPILER (arm-eabi-gcc GNU)
CMAKE_FORCE_CXX_COMPILER (arm-eabi-gcc GNU)

whenever the PROJECT() command is invoked, 
the file Modules/Platform/eCos.cmake is parsed and "executed" several times (3
times on my current configuration).

The net result is that line 45
ADD_DEFINITIONS(-D__ECOS__=1 -D__ECOS=1)
is executed 3 times, and the definitions are appended to each other.

Running CMake with the VERBOSE flag enables shows that the command line is
filled in with the same definitions:
arm-eabi-gcc  -D__ECOS__=1 -D__ECOS=1 -D__ECOS__=1 -D__ECOS=1 -D__ECOS__=1
-D__ECOS=1 ....
