Debian enables PIE hardening flags by default since package gcc-6 6.2.0-7 [1].
With that change, SeaBIOS fails to build with the error below [2][3].
``` $ make Build Kconfig config file Compile checking out/src/misc.o Compile checking out/src/stacks.o src/stacks.c: Assembler messages: src/stacks.c:567: Error: found '(', expected: ')' src/stacks.c:567: Error: junk `(%ebp))' after expression src/stacks.c:568: Warning: indirect call without `*' Makefile:133: die Regel für Ziel „out/src/stacks.o“ scheiterte make: *** [out/src/stacks.o] Fehler 1 ```
Passing `no-pic` to the compiler fixes this issue.
