# GCC uses -G 0 -mabicalls -fpic as default. We don't want PIC in the kernel

# 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.
