Libtool does not know about the system you are building for, does not
know that an underscore is required.

What is the host triplet for the system that you are building for?

You need to set archive_expsym_cmds for that system to be similar to
interix[[3-9]]* which has:

        _LT_AC_TAGVAR(archive_expsym_cmds, $1)='sed "s,^,_," $export_symbols
>$output_objdir/$soname.expsym~$CC -shared $pic_flag $libobjs $deplibs
$compiler_flags ${wl}-h,$soname
${wl}--retain-symbols-file,$output_objdir/$soname.expsym
${wl}--image-base,`expr ${RANDOM-$$} % 4096 / 2 \* 262144 + 1342177280`
-o $lib'

As you can see, it takes the symbol list, prepends and underscore, and
then uses that.

It is not required to change global_symbol_pipe etc.
