    testsuite: refine gcc.dg/analyzer/fd-4.c test for newlib
    
    Contrary to glibc, including stdio.h from newlib defines mode_t which
    conflicts with the test's type definition.
    
    .../gcc/testsuite/gcc.dg/analyzer/fd-4.c:19:3: error: redefinition of typedef 'mode_t' with different type
    ...
    .../include/sys/types.h:189:25: note: previous declaration of 'mode_t' with type 'mode_t' {aka 'unsigned int'}
    
    Defining _MODE_T_DECLARED skips the type definition.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.dg/analyzer/fd-4.c: Fix for newlib.
