[LLVMdev] problem with llvm-config when building 3.1 for Linux-to-Windows cross development

[Eric Smith]

Recently I packaged LLVM 3.0 for cross development use on Fedora Linux 
targeting Windows using MinGW, and submitted it for a Fedora package 
review.  Getting that to build went pretty smoothly.

I just tried to update it to LLVM 3.1 and ran into a problem with 
llvm-config.  When LLVM 3.0 is configured for a Linux host and MinGW 
target, the llvm-config tool is built appropriately to run on the host 
(Linux) system, as is necessary for cross development.  However, it 
seems that with LLVM 3.1, with the same configuration, only a target 
(Windows) llvm-config.exe gets built, which is useless for 
cross-development.

Is there a simple fix to get an appropriate host-based llvm-config built?

Thanks!
Eric
