Tried to modify source after configure;

cp Makefile Makefile.orig
sed '/src_make_prime_list/d' Makefile.orig > Makefile
depbase=$(echo src/make-prime-list.o | sed 's|[^/]*$|.deps/&|;s|\.o$||');\
     cc -std=gnu99 -I. -I./lib -Ilib -I./lib -Isrc -I./src \
     -fdiagnostics-show-option -funit-at-a-time -g -O2 -MT \
     src/make-prime-list.o -MD -MP -MF $depbase.Tpo -c -o src/make-prime-list.o \
     src/make-prime-list.c &&
mv -f $depbase.Tpo $depbase.Po &&
cc -std=gnu99 -fdiagnostics-show-option -funit-at-a-time -g -O2 \
     -Wl,--as-needed -o src/make-prime-list src/make-prime-list.o &&
cp Makefile Makefile.bak
sed -e '/hostname.1/d' Makefile.bak > Makefile

Same error

Looks like issue has been reported for NixOS:

coreutils-8.31 is broken on musl- https://github.com/NixOS/nixpkgs/issues/59934

[dslm4515]

Patching lib/strtod.c allowed build to complete.
