Shooting from the hip (i.e. completely untested):

nonlgpl_LTLIBOBJS="$LTLIBOBJS"
LTLIBOBJS=
gl_MODULES([strdup xalloc], [lgl/], [lgl/m4/], [[LGPL]])
lgpl_LTLIBOBJS="$LTLIBOBJS"
AC_SUBST([lgpl_LTLIBOBJS])
LTLIBOBJS="$nonlgpl_LTLIBOBJS"

gl_MODULES([error progname], [gl/], [gl/m4/])

Some of that hair could probably be factored into the gl_MODULES macro itself.
 There might be assumptions about the content of LTLIBOBJS in automake that
mess this up though...

Cheers,
        Gary.
