./configure fails on freebsd

I get through to
checking build system type... amd64-unknown-freebsd11.0
checking host system type... amd64-unknown-freebsd11.0
configure: error:
You are attempting to build Sage on the FreeBSD operating system
...
as it should have been all along, if I change #! /bin/sh
to bash in the 1st line of configure.
Gory details, if anyone cares:
without this, there are apparent bash-isms in ./configure:
in line 2969/70:
test "x$ac_build_alias" = x &&
ac_build_alias=`$SHELL "$ac_aux_dir/config.guess"`
checking for root user... no
checking build system type... amd64-unknown-freebsd11.0
checking host system type... Invalid configuration `x': machine `x' not recognized
configure: error: bash config/config.sub x failed
So it fails due to a similar problem involving "test" a bit later on.
Specifically, if I replace
if test "x$host_alias" = x; then
ac_cv_host=$ac_cv_build
else
ac_cv_host=`$SHELL "$ac_aux_dir/config.sub" $host_alias` ||
as_fn_error $? "$SHELL $ac_aux_dir/config.sub $host_alias failed" "$LINENO" 5
fi
with
ac_cv_host=`$SHELL "$ac_aux_dir/config.sub" $ac_build_alias` ||
as_fn_error $? "$SHELL $ac_aux_dir/config.sub $ac_build_alias failed" "$LINENO" 5

Any idea what causes this weirdness (perhaps it's just something one has to accept, that /bin/sh has to be very much
like bash nowadays)?
SHELL is set to /usr/local/bin/bash
which is
$ bash --version
GNU bash, version 4.4.12(1)-release (amd64-portbld-freebsd11.0)
