What is the build type of ARM Compute using Oracle Linux 7.9?

I'm compiling PHP on ARM Compute using Oracle Linux 7.9. At the configure step, I get the error message:

configure: error: cannot guess build type; you must specify one

After consulting on StackOverflow, I found the solution is to add --build= parameter on the configure command line. But I don't know what is the build type of ARM Compute using Oracle Linux 7.9?

I used

rpm --eval %{_host}

to get the build type. The returned result is: aarch64-redhat-linux-gnu.

But when I run:

./configure --build=aarch64-redhat-linux-gnu

I received the error:

checking build system type... Invalid configuration `aarch64-redhat-linux-gnu': machine `aarch64-redhat' not recognized
configure: error: /bin/sh ./config.sub aarch64-redhat-linux-gnu failed
