SPARC patch to gcc-3.2.3

[Jiri Gaisler]

I finally managed to track down why gcc-3.x would not create
proper eCos images for sparc targets. It is because the gcc
sparc-elf target has the C++ pragma init_priority disabled by
default! eCos uses this to run the constructors in a
particular order. I have attached a patch if anyone is
interested. With this patch, a tool chain with binutils-2.13,
gcc-3.2.3 and newlib-1.12 is built without problems for
--target=sparc-elf

A pre-built tool-chain for linux hosts (bcc-linux-1.0.9)
is availble from:

http://www.gaisler.se/bin/bcc-linux-1.0.9.tar.bz2

Should be installed in /opt .

The same problem still remains in gcc-3.4.3, but this
gcc version does not build newlib correctly, so sparc
users should stay with gcc-3.2.3 for the time being ...

Jiri.
