Bug#940266: z3: FTBFS on hppa - objects in shared libraries need to be compiled with -fPIC

The default on 32-bit hppa is to generate non-position independent code. It is somewhat more efficient. It uses some different relocations and global data is loaded using global pointer. One doesn't need to load address from got. This runtime model was defined by HP years ago (1980s). Strangely, HP decided to generate PIC code by default for hppa64.

Source: z3 Version: 4.8.4-1 Severity: normal Dear Maintainer, On hppa and some other architectures, objects linked in shared libraries need to be compiled with -fPIC. See for example the following build log: https://buildd.debian.org/status/fetch.php?pkg=z3=hppa=4.8.4-1=1567753798=0 This may not be the best way to fix the problem but adding "export CXXFLAGS=-fPIC" to debian rules results in a successful build of z3 on hppa.
