cmake: set _LARGEFILE_SOURCE=1 to fix a cmake error

```
-- Performing additional configure checks with target flags: -mips32r2;-mabi=32;-D_LARGEFILE_SOURCE;-D_FILE_OFFSET_BITS=64
-- Performing Test COMPILER_RT_HAS_mips_FLOAT16
CMake Error: Parse error in command line argument: _LARGEFILE_SOURCE
 Should be: VAR:type=value
```
