That was a good hint! Indeed iconv is not detected properly on amd64 in the snapshot 2020-11-16, but it was on 0.20.1. For all other ISAs like sparc, sparcv9 and i386 the detection works fine for both compared versions. dam@unstable10x [global]:/home/dam/mgar/pkg/gettext/trunk/work-0.20.1 > find . -name config.h | xargs grep HAVE_ICONV ./solaris10-i386/build-isa-amd64/gettext-0.20.1/gettext-runtime/config.h:#define HAVE_ICONV 1 ./solaris10-i386/build-isa-amd64/gettext-0.20.1/gettext-runtime/config.h:#define HAVE_ICONV_H 1 ./solaris10-i386/build-isa-amd64/gettext-0.20.1/libtextstyle/config.h:#define HAVE_ICONV 1 ./solaris10-i386/build-isa-amd64/gettext-0.20.1/gettext-tools/config.h:#define HAVE_ICONV 1 ./solaris10-i386/build-isa-amd64/gettext-0.20.1/gettext-tools/config.h:#define HAVE_ICONV_H 1 dam@unstable10x [global]:/home/dam/mgar/pkg/gettext/trunk > find work -name config.h | xargs grep HAVE_ICONV work/solaris10-i386/build-isa-amd64/gettext-2020-11-16/gettext-tools/config.h:/* #undef HAVE_ICONV */ work/solaris10-i386/build-isa-amd64/gettext-2020-11-16/gettext-tools/config.h:#define HAVE_ICONV_H 1 work/solaris10-i386/build-isa-amd64/gettext-2020-11-16/gettext-runtime/config.h:/* #undef HAVE_ICONV */ work/solaris10-i386/build-isa-amd64/gettext-2020-11-16/gettext-runtime/config.h:#define HAVE_ICONV_H 1 work/solaris10-i386/build-isa-amd64/gettext-2020-11-16/libtextstyle/config.h:/* #undef HAVE_ICONV */ The failing lines are: 0.20.1: gettext-runtime/config.log configure:19080: /opt/csw/bin/gcc-5.5 -o conftest -O2 -pipe -fno-omit-frame-pointer -m64 -march=opteron -I/opt/csw/include -D_REENTRANT -m64 -march=opteron -L/opt/csw/lib/64 conftest.c /opt/csw/lib/64/libiconv.so -R/opt/csw/lib/64 >&5 2020-11-16: gettext-runtime/config.log configure:19878: /opt/csw/bin/gcc-5.5 -o conftest -O2 -pipe -fno-omit-frame-pointer -m64 -march=opteron -I/opt/csw/include -D_REENTRANT -m64 -march=opteron -L/opt/csw/lib/64 conftest.c /opt/csw/lib/libiconv.so -R/opt/csw/lib >&5 which shows that the library found for amd64 is the wrong 32 bit library /opt/csw/lib/libiconv.so instead of the 64 bit one.

Maybe this is enough for you to already know that is going wrong, if you need more info I will dig deeper in the detection code.
