[patch] Build arm-elf-gdb on mingw host

[Dave Murphy]

When building the bfd/doc directory under mingw/msys chew.c converts 
line endings to crlf.  I've patched so the files are read as binary, 
preventing this conversion.


Currently the rdi-share directory can't be built for a windows native 
host http://sourceware.org/ml/gdb/2005-08/msg00058.html. I've copied the 
embed.mt file, renamed to mingw_embed.mt and removed the parts which 
don't build then patched configure.tgt so that the new .mt file is used 
when building for a mingw host.

SIGTRAP isn't defined in the MinGW headers, I patched remote-sim.c to 
define this if it's not defined.

There are some other problems to deal with to get the debugger working 
with thumb code, my arm-elf toolchain is binutils 2.16.1, gcc 4.0.1 and 
newlib 1.13.0. With this combination gdb doesn't recognise thumb symbols 
in the generated elf, at least when setting breakpoints. Debugging ARM 
only code seems to work well.

The attached patch is against current CVS HEAD. To whomever is 
responsible for getting the gdb sources to a point where such minimal 
patching is required on MinGW, great work, it's very much appreciated.

Dave.
