Log Message:
-----------
2009-10-16 Colin Watson <address@hidden>
* configure.ac (TARGET_CFLAGS): Add -mno-mmx -mno-sse -mno-sse2
-mno-3dnow on x86 architectures. Some toolchains enable these
features by default, but they rely on registers that aren't enabled
in GRUB. Thanks to Vladimir Serbinenko for the suggestion.
