27# From Linux arch/mips/Makefile

29# GCC uses -G 0 -mabicalls -fpic as default. We don't want PIC in the kernel
30# code since it only slows down the whole thing. At some point we might make
31# use of global pointer optimizations but their use of $28 conflicts with
32# the current pointer optimization.
33#
34# The DECStation requires an ECOFF kernel for remote booting, other MIPS
35# machines may also. Since BFD is incredibly buggy with respect to
36# crossformat linking we rely on the elf2ecoff tool for format conversion.
