[PATCH] gdb: add support for handling core dumps on arm-none-eabi

[Fredrik Hederstierna]

Hi,
I did a new patch v3 where I try address all your comments,
stripped alot of more "*ix" stuff, and hopefully the remaining parts are all good for bare metal none core files.
Still I have not done the xmalloc/xfree transform to newer variant, but maybe that can be in another future commit.
And sorry for the git-email mess, I'm still learning to use this feature..
Any comments or feedback are welcome!
Thanks, BR Fredrik
