Could -no-undefined be included in PERL_EXT_LDFLAGS or similar when
configure is run?

It may still be possible to add the "-lperl" option needed under MinGW
and Cygwin automatically. On the Solaris system in question, the
missing symbols are in
/usr/perl5/5.8.4/lib/i86pc-solaris-64int/CORE/libperl.so.1, and doing

/bin/bash ./libtool  --tag=CC    --mode=link cc -D_LARGEFILE_SOURCE
-D_FILE_OFFSET_BITS=64 -D_TS_ERRNO -DVERSION=\"6.0\"
-DXS_VERSION=\"6.0\" "-I/usr/perl5/5.8.4/lib/i86pc-solaris-64int/CORE"
   -module   -o TestXS.la -rpath /home/gavin/local/lib/texinfo
libtool.so TestXS_la-TestXS.lo  -no-undefined
-L/usr/perl5/5.8.4/lib/i86pc-solaris-64int/CORE -lperl

worked with the -no-undefined flag. Now I just have to see if it's
possible to get "-L/usr/perl5/5.8.4/lib/i86pc-solaris-64int/CORE
-lperl" automatically from the output of perl -V.
