[PATCH] Allow building with perfc and perfc_arrays

[Ben Thomas <bthomas@virtualiron.com>]

[-- Attachment #1: Type: text/plain, Size: 303 bytes --]

Attempts to build with either perfc or perfc_arrays fails.  Some of
this is specific to the platform (eg, __x86_64__).  Add simple-minded
fixes to allow building with these options.

This patch resolves these issues and now builds on i386 and x86_64

building with perfc fails -> simple fix
building with perfc and perfc_arrays on x86_64 fails -> do the
     simple-minded thing and just add the missing elements
