$ Configure -de -A append:ld=-lpthread

  -A : manipulate symbol after the platform specific hints have been 
         -A append:symbol=value   append value to symbol
         -A symbol=value          like append:, but with a separating space
         -A define:symbol=value   define symbol to have value
         -A clear:symbol          define symbol to be ''
         -A define:symbol         define symbol to be 'define'
         -A eval:symbol=value     define symbol to be eval of value
         -A prepend:symbol=value  prepend value to symbol
         -A undef:symbol          define symbol to be 'undef'
         -A undef:symbol=         define symbol to be ''
       e.g.:  -A prepend:libswanted='cl pthread '
              -A ccflags=-DSOME_MACRO

I'm also tyring it out right now.
I was also pissed that freebsd 7 only has 5.8.8
