HEADS UP: MAJOR changes to the ports system

[Vladimir Kushnir]

Sorry I know I should have written PR but I'm not sure about correct fix.
So here it goes.
After these changes lang/perl5.8 is still linked to libc_r when compiled
with "WITH_THREADS=yes": it's hardcoded in perl-5.8.2/hints/freebsd.sh
Easily fixed with this patch:

  case "$usethreads" in
  $define|true|[yY]*)
!         lc_r=`/sbin/ldconfig -r|grep ':-lc_r'|awk '{print $NF}'|sed -n '$p'`
          case "$osvers" in
  	0*|1*|2.0*|2.1*)   cat <<EOM >&4
  I did not know that FreeBSD $osvers supports POSIX threads.

But i) It requires very recent -CURRENT (I just don't khow how to
distinguish in an elegant way in shell script); and ii) This way
libperl.so and the progs are linked with "-lpthread -lc" (in this order).
Is this correct?
