it is a hppa-specific issue that is being actively tackled by gcc
upstream maintainers, but unfortunately the fix won't make it into
woody.
How to do this depends a bit on how your package works, usually
something like this works with autoconf based packages.
In debian/rules:
DEB_BUILD_ARCH := $(shell dpkg-architecture -qDEB_BUILD_ARCH)
ifeq ($(DEB_BUILD_ARCH),hppa)
CFLAGS="-g -O2 -ffunction-sections"
else
CFLAGS="-g -O2"
endif
and then run configure like this:
CFLAGS=$(CFLAGS) ./configure --whatever-options-you-need
you may need to use CXXFLAGS instead of CFLAGS for C++ packages.
iirc, pike7 has the function-sections fix. you can use it as a
reference.
