superh sh4 crosscompile

sh4crosscompile

Setting up a SH4 SuperH cross compilation environment with a couple pecularities. Mainly I want to cross compile for a much older system/target.

Workstation: Ubuntu 11.10
Target: sh4 gcc-3.3.6 glibc-2.2.5 kernel-2.4.20

ISSUE 1: *** These critical programs are missing or too old: gcc
To fix edit patches/glibc-2.2.5/glibc-2.2.5-allow-gcc-4.0-configure.patch to support he host gcc version. 

ISSUE 2: "In function ‘open’, inlined from ‘collect_execute’ at"
