Fwd: cross-gdb with expat support

[Thomas T <thomasmailinglists9 at gmail dot com>]

FYI, with the following two patches I build a working Microsoft
Windows cross compile toolchain including GDB.

Hi,

as a lot of others before I have a problem to compile a toolchain with
a cross-gdb. I try to build a toolchain for

[EXTRA]      build  = x86_64-unknown-linux-gnu
[EXTRA]      host   = x86_64-w64-mingw32
[EXTRA]      target = arm-none-linux-gnueabihf

The first problem I solved by myself. I removed the multiple
definitions of caddr_t.

But now I fail to build the static cross-gdb, with the well known
error "expat is missing or unusable". Crosstool-NG is the newest one
1.20, I also tried git/master. I already looked for a patch/ideas at
the mailing list, patchwork, google, tried several changes in
300-gdb.sh but didn't found a solution...

The build PC runs on Ubuntu 14.04. And, even I do not know if it is
required as the host is a WindowsPC I installed libexpat1-dev.

Is there currently a well known problem? Which additional infos shall
I provide, any ideas?

Best Regards
Thomas
