For Arm toolchain build, Mbed 2(classic) programs occur an unexpected error if there is "#include "mem_XXXX.h"" in the script file.
It seems that the linker script can't find the include file because "mem_XXXX.h" file is not in the same path with the linker script.
(Refer to Issue #6975.)
To address this issue, I remove inclusion processing and define the related macros at ARMCC linker script file.
