The arm64 makefile sets the -mabi=lp64 CFLAG. It appears this ABI argument was added to GCC in 4.9 for AArch64. CentOS 7 / RHEL7 ship with GCC 4.8.
Compiling via
without this flag in 4.8.5 results in the error:
Compiling natively
on a aarch64 machine results in a similar error with the flag removed:
