I've tried your patch on a debian unstable machine with gcc-4.0.3,
2.16.1cvs20060117-1 and glibc-2.3.6-7 and get this error from the glibc
startfiles stage: 

running configure fragment for ports/sysdeps/unix/sysv/linux/arm/eabi/nptl
running configure fragment for ports/sysdeps/unix/sysv/linux/arm/eabi
running configure fragment for nptl/sysdeps/pthread
configure: error: working compiler support for visibility attribute is required

Did you see the problem above with the "old" toolchains?
