description:
make a version of the GCC 7 gcc/config/arm/arm.h change for arm64
so that this package builds on arm64 platforms.

this change probably can be copied into the main GCC 7 package too.

no pkg bump as this should only enable building where it was not
working already.

+driver-aarch64.o is not included for NetBSD and it is responsible for
+the definition of host_detect_local_cpu.
+
+Without it, we get an undefined reference.
+
+Similar to GCC bugzilla #77800 for arm.
