Charles,
I am not sure to follow your explanation.

on cygwin

$cd /usr/lib
$ grep libdir *.la
libFLAC++.la:libdir='/usr/lib'
libFLAC.la:libdir='/usr/lib'
libGraphicsMagick++.la:libdir='/usr/lib'
libGraphicsMagick.la:libdir='/usr/lib'
libGraphicsMagickWand.la:libdir='/usr/lib'
libICE.la:libdir='/usr/lib'
libMagick++.la:libdir='/usr/lib'
libMagickCore.la:libdir='/usr/lib'
libMagickWand.la:libdir='/usr/lib'
libMrm.la:libdir='/usr/lib'
libSM.la:libdir='/usr/lib'
libUil.la:libdir='/usr/lib'
libX11.la:libdir='/usr/lib'
libXau.la:libdir='/usr/lib'
libXaw7.la:libdir='/usr/lib'
and so on.....

there is no libdir='=/.......

and on my build
$ find . -name *.la -exec grep libdir \{\} \;
libdir='/usr/local/lib/octave-3.3.52+'
libdir=''
libdir='/usr/local/lib/octave-3.3.52+'
....

On my humble understanding

libdir is a variable with the name of the directory,
I never saw and not found in libtool documentation

libdir='=/.......

could you point me to some documentation about it ?
