Subject: 28.0.50; `./configure --native-compilation` fails on FreeBSD if
 'porttools' is installed
Date: Mon, 30 Aug 2021 07:48:02 +0900 (JST)

There is an port/package named 'porttools' in FreeBSD Ports/Packages
Collections. it includes shell script named `port`, and if it is
installed, `./configure --native-compilation` fails as following.

----------------------------------------------------------------------

I checked configure.ac and found following lines.

----------------------------------------------------------------------
# Check MacPorts on macOS.
AC_PATH_PROG(HAVE_MACPORTS, port)
----------------------------------------------------------------------

It means that configure script regards that OS is macOS and MacPorts
is installed if it finds `port` command in you PATH. As I wrote above
'porttools' package installs shell script named `port`. So if you
execute configure script on FreeBSD system that 'porttools' package is
installed, then it misinterprets thet OS is macOS and fails to detect
libgccjit. In fact configure script works fine if this line is
commented out.

According to my study about MacPorts,

1. MacPorts only works with macOS
2. If MacPort is installed, `port` command is used to interact with
   MacPorts.

So configure script should work as is expected even if the above lines
are chanaged as following.

----------------------------------------------------------------------
# Check MacPorts on macOS.
if test $opsys = darwin; then
  AC_PATH_PROG(HAVE_MACPORTS, port)
fi
----------------------------------------------------------------------

And it also prevents `port` command installed in non-macOS system from
being misdetected as the evidence that OS is macOS.
