Currently, this patch wouldn't help me. I looked at my system in detail 
and realized, that unfortunately I don't have static libraries for lots 
of dependencies and have to compile everything dynamically. When I 
switch off "static toolchain" I can build everything almost without a 
problem. Well - almost - because I had to patch ppl-0.10.2 (just like 
0.11.2 already done for std::ptrdiff_t)... in the end, there are at 
least two patches (another one for duma on mingw) and I'd like to 
contribute them, when I'm completely done with testing.

The question now regarding static toolchain is, if it's reasonable to 
pull some more static dependencies into the crosstool-ng, like flex, 
ncurses (for gdb) and probably some other?

However, thank you very much for your help and this important tool,
Filipp
