collect information about internal compiler errors (ICEs) and attach them to the build log

[Matthias Klose]

current GCC versions create a preprocessed source file an put it into /tmp. Please make this available outside the buildd.

$ g++-4.1 -c -O 3ddeskd.ii
3ddeskd.cpp: In function 'void draw_digit(int, float, float)':
3ddeskd.cpp:634: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
For Debian GNU/Linux specific bug reporting instructions,
see <URL:file:///usr/share/doc/gcc-4.1/README.Bugs>.
Preprocessed source stored into /tmp/ccOWsdYn.out file, please attach this to your bugreport.

The last line can be used to find that file.

I'll look at how much of this I can implement on my side before I need an LP hacker to look at anything server-side.
