Fix a few cmake configure-time checks.

Browse Source 
A couple of actual checks were missing (elf_aux_info, sysctlbyname).
Several more were accidentally left out of cmake.h.in, meaning they
wouldn't be propagated from cmake's variable space into the actual
compilation. And a handful of checks in the C source were still using
the autotools-style 'if defined' in place of the cmake-style "it's
always 0 or 1" plain #if.
