It didn't.

The exports.h file I have (when the make stops) contain empty defines:

#define  ccif_add_to_sort       
#define  ccif_block_by_index    
#define  ccif_block_by_name     
#define  ccif_close_cif 

If I replace this with your exports.h file the compilations stops at:

        if test -f so_locations; then cp -f so_locations /tmp; fi; \
                                     ld -64 -shared -all \
                                           -exports_file libccif.exp
libccif.a \
                                           -update_registry

                                            -o libccif.so; \
                                     cp -f /tmp/so_locations . ; rm -f

Compiling a simple program like:

#include <stdio.h>

test1()
{
  printf("test1\n");
}

test2()
{
  printf("test2\n");
}

main()
{
  test1();
  test2();
}

Running nm -h on the .o file produces:

...debug_frame    d       0       0
...debug_aranges  d       0       0
...debug_pubnames         d       0       0

...srdata         r       0       0
test1   T       0       60
printf  U       0       0
...debug_line     d       0       0
...debug_info     d       0       0
test2   T       64      60
main    T       128     72

Looks like that trailing underscores aren't necessary,
so I removed them from the exports.h file, but I still get:
