NEON SIMD for EC dynamic support is not detected on aarch64

[potatogim]

Description of problem:

Hello!

I'm trying to build GlusterFS under aarch64 with Koji environment but NEON SIMD for EC dynamic support is not detected like below.

+ ./configure --build=aarch64-koji-linux-gnu --host=aarch64-koji-linux-gnu --program-prefix= --disable-dependency-tracking --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib64 --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/var/lib --mandir=/usr/share/man --infodir=/usr/share/info --enable-firewalld --with-tmpfilesdir=/usr/lib/tmpfiles.d --disable-linux-io_uring --without-libtirpc --without-tcmalloc
