Actually, I'm a bit confused. Shouldn't FLAT binaries be PIE ? Since
there's no MMU, each binary will be loaded at a different address, so
binaries should be PIE, no?
But the original reason why I removed -pie is because of:
For the exact same error, Mike Frysinger says to remove the -pie flag.
Hum, http://www.kdvelectronics.eu/uClinux-cisco2500/exotica.html seems
to indicate that PIE is not required in all cases for FLAT binaries.
I would tend to trust Mike Frysinger on this, though :)
