sys-boot/silo: fix a build against PIC profiles

Build failed on default/linux/sparc/17.0 profiles as
  ./util -a silotftp.map silotftp.aout silotftp2.aout silotftp.b silotftp.b2
  Distance between two changes larger than 63K 3 83881 0

I suspect th breakage happens due code inflation (caused by
-fPIC) on new profiles. iamben reports that -fno-PIC makes
silo to build and boot a sparc machine \o/
