I guess his libtool in PATH is simply not Apple's...
So presumably an upstream bug.
P.S.: From Singular's spkg-install:
if [ "$UNAME" = "Darwin" ]; then
# Singular needs $LD set to "libtool", not "ld" on Darwin.
# If we unset it, Singular will figure it out correctly.
unset LD

So we'd have to change the "figures it out correctly"... ;-)
Yep, it doesn't "figure it out", it hardcodes 'libtool' on Darwin:
ix86Mac-darwin)
AC_CHECK_LIB(dl, dlopen)
if test "$ac_cv_lib_dl_dlopen" = yes; then
LD_DYN_FLAGS1="-dynamic"
LD_DYN_FLAGS2="-ldl"
SFLAGS="-fpic -DPIC"
SLDFLAGS="-dynamic -twolevel_namespace
-weak_reference_mismatches weak -undefined dynamic_lookup"
if test "${LD+set}" != set; then
LD=libtool
fi
ac_lib_dl=yes
fi
;;
x86_64Mac-darwin)
AC_CHECK_LIB(dl, dlopen)
if test "$ac_cv_lib_dl_dlopen" = yes; then

... but only in singular-3.1.6.p1/src/latest/Singular/configure.in.
So I'd say blindly using 'libtool' (and assuming it is Apple's) is an
upstream bug.

Still wonder why Singular (meanwhile) directly uses $LD exactly once;
everything else gets linked with GCC (g++ that is).

P.P.S.: Haven't found anything in the (configure) logs indicating what
"linker" Singular decided to use, nor any checks related to that.
