llvm dev - Jan 2014 - [LLVMdev] Failed to building (svn/git/dev version) cross-compiling for powerpc

I'm interested in PowerPC development and I tried to build LLVM for
cross-compiling today and I got the following error:

> [ 94%] Building CXX object
tools/llvm-config/CMakeFiles/llvm-config.dir/llvm-config.cpp.o

I don't know how to fix and I'd appreciate any help.

The options I used to compile were:

> cmake ../.. -DCMAKE_CROSSCOMPILING=True
> -DLLVM_DEFAULT_TARGET_TRIPLE=ppc-linux-gnu -DLLVM_TARGET_ARCH=powerpc

The "version" I'm using is from the git mirror:

I already have a "normal" (non cross-compiling) and stable (3.4) llvm
installed on my system (ArchLinux, where everything is at the latest
release, there is no separation of *-dev packages and they avoid to
apply local patches on top of upstream code).

I figured out my problem. I solved it using:

cmake -DPYTHON_EXECUTABLE=/usr/bin/python2

So, it wasn't related to cross-compiling at all.

For anyone who encounters a problem with similar characteristics, the
solution could be the same.
