OK, that's probably because I had removed -shared fron pkg-perl.mk and
forgot about it.

I tried to set TARGET_LDFLAGS="-g" since -g is simply ignored by ld, and
I left the -shared in lddlflags on the configure line, but then, here's
what I got:
    arm-linux-gnueabihf-gcc: error: unrecognized command line option ‘-shared -g’

Bummer! So, if we pass more than one option to --lddlflags, the perl
infra completely derails, and sets LDDLFLAGS in the Makefile, to:
    LDDLFLAGS = '-shared -g'

Bad, real bad... :-(

OK, let's see what happens to other extensions. What about
perl-mojolicious? Here's what LDDLFLAGS looks like with -shared on the
configure line, and TARGET_LDFLAGS=-g:
    LDDLFLAGS = -shared -g

Oooookay... And other extensions are OK, too.

So, that's not the perl infra that is brain-dead, that's really
perl-net-ssleay which is completely f*cked up... :-(

OK, I'll revive your patch, with a few quirks...

Regards,
Yann E. MORIN.
