If there are 10000 files it might look at 10000 different places including
device names.... kernel names, shell features, kernel modules and more.
i.e all the things that 'configure' might know about and more.

/etc/redhat-release is the most common.   N.B. You may need to restore
the CentOS words often to permit CentOS updates to do the right thing.

If /etc/redhat-release is not the answer you may have to look harder at the
failing process with strace  or even SELinux tricks to see what it does
look at.

If it is Oracle, Given the price of Oracle -- just purchase the RH product.
It is common that the expensive packages are the most restrictive and putative.
