+# 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.
