#68742: Build does not respect CONFIG_SITE

--------------------+--------------------
 In the world of the autotools, it is common to use a CONFIG_SITE to
 specify parameters to the configure script.  There is something about the
 current macports build that does not play well with this.  If the
 environment variable CONFIG_SITE is set to a path containing the text
 "prefix=/p/a/t/h", then the build (checked out at
 ddc57c5f6ced9ccc0bb4e04e22e218ae851c241d) fails.  To be specific:

 export CONFIG_SITE=/some/path
 echo 'prefix=/p/a/t/h' > $CONFIG_SITE
 ./configure
 make

 fails with an error like:

 chmod: ${PWD}/vendor/vendor-destroot/p/a/t/h/libexec/macports/lib/tcllib*:
 No such file or directory

 The build works fine if the config site is not used but instead the user
 invokes the configure script with the prefix specified as an argument.
