aarch64 build release problem

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

In case one sets RELEASEMACHINEDIR=${MACHINE}-${MACHINE_ARCH}

should

$ cat /usr/src/sys/stand/efiboot/bootaa64/Makefile 
# $NetBSD: Makefile,v 1.5 2018/10/28 10:17:47 jmcneill Exp $

PROG=           bootaa64.efi
OBJFMT=         binary
NEWVERSWHAT=    "EFI Boot (aarch64)"

EXTRA_SOURCES=  efibootaa64.c
EXTRA_SOURCES+= cache.S

release: check_RELEASEDIR
        ${HOST_INSTALL_FILE} -m ${BINMODE} ${PROG} \
                ${RELEASEDIR}/${MACHINE}/installation/misc
                              ^^^^^^^^^^
MACHINE read RELEASEMACHINEDIR ?
