>Description:
Many ports defer setting of PKGNAMEPREFIX, basing it upon variables set in other parts of the ports infrastructure.  This can result in differing values for ${OPTIONSFILE} between when the WITH_ and WITHOUT_ variables are set, and when the config target is run, meaning that any options set for such ports are ignored.

>How-To-Repeat:
Consider www/mod_musicindex.  Its Makefile contains:

#v+
PKGNAMEPREFIX=  ${APACHE_PKGNAMEPREFIX}
...
USE_APACHE=     2.0+
#v-

The WITH_ and WITHOUT_ variables are set before the bsd.apache.mk is included, giving an expansion of /var/db/ports/mod_musicindex/options for ${OPTIONSFILE}.  However, when the config or showconfig targets are run, bsd.apache.mk has now been included, giving an expansion of /var/db/ports/ap20-mod_musicindex/options for ${OPTIONSFILE}.

#v+
# cd /usr/ports/www/mod_musicindex
# make rmconfig
# make showconfig
===> The following configuration options are available for ap20-mod_musicindex-1.3.3_2:
     NLS=on (default) "Native language support"
     FLAC=off (default) "FLAC support"
     MP3=on (default) "MP3 support"
     MP4=off (default) "MP4 support"
     VORBIS=off (default) "Ogg/Vorbis support"
     LIBARCHIVE=on (default) "Archive downloading support"
     FILECACHE=on (default) "Caching support"
===> Use 'make config' to modify these settings
# make -V WITH_MP4

# make -V WITHOUT_MP4
true
# make config (enable MP4)
# make showconfig
