rc3 chokes on intel nocona chip

Using the src.rpm on Fedora 8:

............
checking for vlineColor in -lSDL_gfx... no
checking Architecture... x86_64
checking if C compiler accepts inline MMX assembly... yes
checking sub-architecture settings... Your  does not even support "i386" 
for '-march' and -mtune.
checking what warning flags to pass to the C compiler... -Wall -Wunused
............

and then, it uses the warning for CFLAGS:

......................
  gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../../utils Your does 
not even support i386 for -march and -mtune. -O2 -fPIC -funswitch-loops 
-ftree-vectorize -fvisibility-inlines-hidden -mtune=nocona -pipe 
-frename-registers -pthread -Wall -Wunused -MT build_sub22_mests.lo -MD 
-MP -MF .deps/build_sub22_mests.Tpo -c build_sub22_mests.c  -fPIC -DPIC 
-o .libs/build_sub22_mests.o
gcc: Your: No such file or directory
gcc: does: No such file or directory
gcc: not: No such file or directory
gcc: even: No such file or directory

It's not an exotic cpu:

Clearly cpuinfo.sh doesn't like it:

sh -x cpuinfo.sh:
...........

+ test pentium4 = athlon64
+ test pentium4 = athlon-xp
+ test pentium4 = athlon-4

+ test error = error
+ echo 'Your  does not even support "i386" for '\''-march'\'' and -mtune.'
Your  does not even support "i386" for '-march' and -mtune.
...........

In any event, the error message from cpuinfo.sh shouldn't be used as 
CFLAG. I couldn't see where Makefile picked it up.
