ld: fatal: option --version-script requires option -z gnu-version-script-compat
to be specified
"""

Looks like solaris' ld needs extra `–z gnu-version-script-compat` option set to
make `–version-script` work:

https://docs.oracle.com/cd/E88353_01/html/E37839/ld-1.html says we need an
extra  option 
"""
–z gnu-version-script=mapfile
–z gnu-version-script-compat
–version-script mapfile

    Provides partial support for the GNU version script style of mapfile.
Version scripts are based on the original Solaris version 1 symbol definition
syntax, with some extensions. ld supports the most common such extension, the
use of wildcard characters in the specified symbol names. Other GNU-specific
extensions may not be supported. ld will issue an appropriate error if an
unsupported extension is encountered.

    For convenience in building software developed with GNU version scripts,
the native GNU –version-script option is accepted as an alias for –z
gnu-version-script. Due to the partial nature of the support for GNU version
scripts, the use of –version-script must be explicitly enabled by specifying –z
gnu-version-script-compat.
"""

libctf/configure.ac has too simplistic detection of --version-script and
probably will need to be extended:

"""
# Use a version script, if possible, or an -export-symbols-regex otherwise.
VERSION_FLAGS='-export-symbols-regex ctf_.*'
if $LD --help 2>&1 | grep -- --version-script >/dev/null; then
    VERSION_FLAGS="-Wl,--version-script='$srcdir/libctf.ver'"
fi
AC_SUBST(VERSION_FLAGS)
"""
