configure mistakenly adding "-link -dll" option on a linux system lead to errors

[samfux84]

Hi,

I am trying to compile adol-c on a linux system (CentOS 7.9) and after configuring the build with

./configure --prefix=/cluster/apps/nss/gcc-6.3.0/adol-c/2.7.2/x86_64 --enable-shard --enable-sparse --enable-atrig-erf

and when compiling the code afterwards, it always fails with the error "ld: cannot find -link":

/bin/sh ../libtool  --tag=CXX   --mode=link /cluster/spack/apps/linux-centos7-x86_64/gcc-4.8.5/gcc-6.3.0-sqhtfh32p5gerbkvi5hih7cfvcpmewvj/bin/g++  -g -O2 -version-info 4:0:2 -no-undefined   -o libadolc.la -rpath /cluster/apps/nss/gcc-6.3.0/adol-c/2.7.2/x86_64/lib64 dummy.lo src/libadolcsrc.la   src/drivers/libdrivers.la src/tapedoc/libtapedoc.la src/lie/liblie.la src/sparse/libsparse.la -lm

/cluster/apps/sfos/bin/ld: cannot find -link

For some reason the linker is not correctly recognized by the configure script and therefore the options "-link -dll" are added.
