Actually, I remember a problem of this nature relating to performing
the build in a subdir of the source too.  Build it totally out of the
source tree.  Really, you might be suprised.

Just so you know, I've built 1.0.2 & the latest code on HPs with
--enable-shared.   In fact it's worth noting HP's are my primary
development platform :-0

You have to configure gcc to use gas.  Otherwise it assumes the
HP assembler by default and disables -g support.

No, -fpic is not safe here.  -fpic should only be used by user
built libraries -- never by compiler runtime support libraries
or libraries shipped to customers.

Trust me on this..  In fact, I just spent quite a bit of time
analyzing a problem for a Cygnus customer where they could not
link their application because a vendor which shipped them libraries
compiled them with -fpic instead of -fPIC.
