Sigh. ZSH does really stupid things. All of these variables are
basically forced to be some internal value and cannot be overridden:

CPUTYPE MACHTYPE OSTYPE VENDOR TMPPREFIX TIMEFMT WATCHFMT LISTMAX
KEYTIMEOUT LOGCHECK MAILCHECK

This means CPUTYPE= has no affect in buildenv and you end up with the
host's value there, which breaks compiling.

From ZSH (not buildenv):
# env|grep CPUTYPE
# echo $CPUTYPE
amd64
# env -i /usr/local/bin/zsh -c env|grep CPUTYPE
# env -i CPUTYPE=foo /usr/local/bin/zsh -c env|grep CPUTYPE
CPUTYPE=amd64
