[build] Prevent gcc from creating position-independent 32-bit code

Some possibly-patched versions of gcc (observed with gcc 6.3.0 on Debian Stretch and with gcc 7.2.0 on Arch) seem to default to creating position-independent code. This results in GOT relocation records which are not handled by efireloc, causing a build failure. Fix by adding -fno-pic to the 32-bit build options.
