Once I added -shared to the link line for Perl 5.8.0, eg.
LDDLFLAGS = -Wl,-E -G -L/usr/local/lib -L/usr/lib/pic/sparcv9 -shared
I was able to get Perl to build successfully and install.
Adding this option also adds it to the default Makefile settings for
subsequently compiled perl modules:
lddlflags=' -Wl,-E -G -L/usr/local/lib -L/usr/lib/pic/sparcv9 -shared'
and this together with a properly configured 64-bit Perl made
everything work. (Presumably a 32-bit perl with modules compiled
32-bit would work as well, just have to make sure to include -shared)
