* config/mips/linux.h (NEED_INDICATE_EXEC_STACK): Define to
TARGET_SOFT_FLOAT.
* config/mips/mips.c (TARGET_ASM_FILE_END): Define to ...
(mips_asm_file_end): New function. Delegate to
file_end_indicate_exec_stack if NEED_INDICATE_EXEC_STACK is true.
* config/mips/mips.h (NEED_INDICATE_EXEC_STACK): Define to 0.
