Summary:                    CMAKE_LD_FLAGS from toolchain is ignored by
compiler's check
Description: 
I want to use gcc's thread sanitizer. I have toolchain.cmake

set (CMAKE_SYSTEM_NAME "Linux")
set (CMAKE_C_COMPILER "gcc-4.8.3")
set (CMAKE_C_FLAGS "-fPIE -Werror -Wno-maybe-uninitialized -fsanitize=thread
-fno-omit-frame-pointer" CACHE STRING "gcc-4.8.3 thread cflags")
set (CMAKE_LD_FLAGS "-pie")

Steps to Reproduce: 
cmake -DCMAKE_TOOLCHAIN_FILE=../toolchain.cmake ..

/usr/bin/gcc-4.8.3 -fPIE -Werror -Wno-maybe-uninitialized -fsanitize=thread
-fno-omit-frame-pointer
CMakeFiles/cmTryCompileExec3265698553.dir/testCCompiler.c.o -o
cmTryCompileExec3265698553 -rdynamic

gcc-4.8.3: error: -fsanitize=thread linking must be done with -pie or -shared

CMAKE_C_FLAGS works, but CMAKE_LD_FLAGS is ignored.
