sparc and alpha fixes

[Jakub B. <qb...@pl...>]

Hello,

The attached patches fix the following issues:
- missing prototypes in sparc syscall list (needed to build current
  strace on sparc) (newsysc patch)
- some mistakes in alpha and sparc syscall lists (getdents64,
  newsysc patches)
- sparc64 compilation errors (sparc64 patch)

Updated and tested against strace 4.5.16.
