I think gcc-3.4.x has fixes for arm that earlier versions lack.
If you can live with it, please do.
(Do try gcc-3.4.1, too.)

The patches/gcc-3.3.4 directory in crosstool is still fairly empty;
you might need to copy some patches from ../gcc-3.3.3.  But gcc-3.3.3
wasn't happy either for you, so I guess that's not it.
I don't know why 3.3.3 didn't build...

gcc-3.5 is not yet ready for prime time (I can't build glibc with it).

BTW, here's the build matrix from crosstool-0.28-rc28 (nothing much has
changed since then, so I don't know why your build of 3.3.3 failed...)

Tested combinations:

A: gcc-2.95.3 glibc-2.1.3 binutils-2.13.90.0.2 linux-2.4.21
B: gcc-2.95.3 glibc-2.2.5 binutils-2.11.2      linux-2.4.3
C: gcc-3.3.3  glibc-2.1.3 binutils-2.15        linux-2.4.24
D: gcc-3.3.3  glibc-2.2.5 binutils-2.15        linux-2.4.21
E: gcc-3.3.3  glibc-2.3.2 binutils-2.15        linux-2.4.24
F: gcc-3.4.0  glibc-2.1.3 binutils-2.15        linux-2.4.21
G: gcc-3.4.0  glibc-2.2.5 binutils-2.15        linux-2.4.21
H: gcc-3.4.0  glibc-2.3.2 binutils-2.15        linux-2.6.6
