site/ix86-common: Drop ac_cv_sizeof_ino_t as it can be incorrect with large file support
Depending on whether large file support is enabled, the size of ino_t can
be 4 or 8 on 32 bit x86. Drop the value from the site cache and allow the
system to vary it depending on configuration. Very few other arches actually set
this so its likely obsolete and doesn't need to be hardcoded anymore.
Also drop the 64 bit and x32 variants since autodetection of this value appears
to work fine and this avoids any confusion or sizing errors depending on large
file support.
