Revert "site: merged common-glibc from OE"

This reverts commit a2f942c22e31fe15fef1b44a0e5cc548a60d43a6.

AC_TYPE_UID_T autoconf macro caches its result in ac_cv_type_uid_t
for defining uid_t and gid_t to suitable types if system headers do not
define them

back in 2008 autoconf did not evaluate it correctly [1] however it works
fine now with autoconf 2.72c especially after [2]
