When running test-case gdb.base/unwind-on-each-insn-amd64-2.exp with target board unix/-fPIE/-pie, I run into: ... gdb compile failed, ld: unwind-on-each-insn-amd64-21.o: relocation \ R_X86_64_32S against `.text' can not be used when making a PIE object; \ recompile with -fPIE ld: failed to set dynamic section sizes: bad value ... Fix this by hardcoding nopie in the test-case, and for good measure in the other test-cases that source unwind-on-each-insn.exp.tcl and use a .s file. Tested on x86_64-linux.
