--- Comment #8 from Manfred Schwarb <manfred99 at gmx dot ch> ---
Works for me, the error message is gone.
I inserted a pair of set -x/set +x around the gold configure block,
and the following is the output, everything looks OK:
original:
+ test set = set
+ :
+ enableval=yes
+ case "${enableval}" in
+ test x '!=' x
+ gcc_cv_gld_major_version=
+ gcc_cv_gld_minor_version=
++ echo ../../gfortran-source/gcc-5-20140817/gcc
++ sed -e 's,/gcc$,,'
+ gcc_cv_ld_gld_srcdir=../../gfortran-source/gcc-5-20140817/ld
