Change errnoent.h files to use designated initializers

* signal.c (printsiginfo): Allow elements of errnoent array to be zero.
* syscall.c (trace_syscall_exiting): Likewise.
* errnoent.sh: Output designated initializers.
* linux/errnoent.h: Regenerated.
* linux/alpha/errnoent.h: Regenerated.
* linux/hppa/errnoent.h: Regenerated.
* linux/mips/errnoent.h: Regenerated.
* linux/sparc/errnoent.h: Regenerated.
* linux/sparc/errnoent1.h: Regenerated.
* linux/powerpc/errnoent.h: New file.
* linux/powerpc64/errnoent.h: Include "powerpc/errnoent.h".
* Makefile.am (EXTRA_DIST): Add linux/powerpc/errnoent.h
and linux/powerpc64/errnoent.h.
