aarch64-none-elf-gcc and related programs will not install

Hi,

context: 12.0-CURRENT #0 r336037 amd64 / ports r474140

I get the following when installing aarch64-none-elf-gcc and related 
programs from ports. It will build fine, just errors on install.

my /etc/make.conf looks like this:

 > less /etc/make.conf
WRKDIRPREFIX=/buildports
MAKE_JOBS_NUMBER=36
WITH_CCACHE_BUILD=YES
CCACHE_DIR=/ccache
WITH_MANCOMPRESS=YES
WITHOUT_DEBUG=YES
OPTIONS_SET+=OPTIMIZED_CFLAGS
OPTIONS_SET+=ICONV
CPUTYPE?=sandybridge

It doesn't matter if /etc/make.conf is moved out of the way.

these also fail in a similar way:
devel/arm-none-eabi-gcc
sysutils/u-boot-rpi2
sysutils/u-boot-rpi3

output when trying to install:
