On GCC builds

[pete@ltoi.iap.physik.tu-darmstadt.de]

 About GCC builds on the Distributions SuSE-4.2, 6.1, 6.2 & 7.3:

   [g]libc    2.95.x  3.0.x  3.1.x         host              Kernel      SuSE

    5.2.18      ok    FAIL   FAIL(?)  i586-pc-linux-gnu     2.0.5 & 39   4.2

    2.0.7       ok    FAIL   FAIL     i586-pc-linux-gnu     2.2.19       6.1

    2.1.1       ok     ok    FAIL^*   i586-pc-linux-gnu     2.2.20       6.2

    2.1.1       ok     ok     ok      i686-pc-linux-gnu     2.2.20       6.2

    2.2.4       ok     ok     ok      i686-pc-linux-gnu     2.4.10-4GB   7.3

 Kernel's may be newer than the one from the distro.

 -> Flaws in support for older glibc & host's in current GCC?

 ^*: needs newer binutils. See below.

     Configure with {for example}:

     --with-as=/usr/local/bin/as --with-ld=/usr/local/bin/ld

     where:

         > /usr/local/bin/ld -v
         GNU ld version 2.11.2 (with BFD 2.11.2)

     whereas the GCC configure script defaults to:

         > /usr/bin/ld -v
         GNU ld version 2.9.1 (with BFD 2.9.1.0.25)

     i.e. the version from the SuSE-6.2 distro,
     which will not work on i586.

gcc-3.1 on i586 needs newer binutils than for i686 ... (?)

Note: FAIL's on glibc-2.0.7/i586 & older are due to other reasons.
