# GCC uses -G 0 -mabicalls -fpic as default.  We don't want PIC in the kernel
# code since it only slows down the whole thing.  At some point we might make
# use of global pointer optimizations but their use of $28 conflicts with
# the current pointer optimization.
#
# The DECStation requires an ECOFF kernel for remote booting, other MIPS
# machines may also.  Since BFD is incredibly buggy with respect to
# crossformat linking we rely on the elf2ecoff tool for format conversion.

# On the other hand, we want PIC in the U-Boot code to relocate it from ROM
