[Bug c/14053] New: second stage build errors (--with-cpu=601)

["stefaan dot simoens at tiscali dot be" <gcc-bugzilla at gcc dot gnu dot org>]

I edited gcc/config/rs6000/sysv4.h to
#define ASM_DEFAULT_SPEC "=m601" (PR 14037)

The make bootstrap fails in stage2 ...

I actually began investigating the 3.3.3-prerelease because I found errors in 
binaries built/optimized with -mcpu=601. (For example: latest binutils gives 
errors in 'make check' for the ld tests when I build with -mcpu=601; everything 
runs fine if I don't add the -mcpu=601). Any ideas? I'd be glad to be of any 
help (but i'm not a programmer...)
