Libgomp test-case libgomp.c/target-5.c is failing to compile when building for
x86_64 with nvptx accelerator due to missing:
- getpid
- gethostname
- isatty (pulled in by fwrite)
in the nvptx newlib.
This patch fixes the build failure by:
- adding a function gomp_print_string which limits the use of fwrite to a single
location (in affinity-fmt.c), and
- creating an nvptx version of affinity-fmt.c, which:
- overrides the configure test results HAVE_GETPID and HAVE_GETHOSTNAME, and
- implements fwrite using write.
Build and reg-tested on x86_64 with nvptx accelerator.

* affinity-fmt.c (gomp_print_string): New function, factored out of ...
(omp_display_affinity, gomp_display_affinity_thread): ... here, and ...
* fortran.c (omp_display_affinity_): ... here.
* libgomp.h (gomp_print_string): Declare.
* config/nvptx/affinity-fmt.c: New file. Include affinity-fmt.c,
undefining HAVE_GETPID and HAVE_GETHOSTNAME, and mapping fwrite to
write.
