To me, this looks more like a cross-compile problem than a physfs  
problem. Why are you specifying --target? I thought that option makes  
only sense for code-generating programs such as gcc and binutils. I  
would specify --build and --host, --build being the machine where you  
run configure and make, and --host being the machine where you intend  
to run the compiled program on. For --build, just add what ./ 
config.guess outputs.

Hope that helps,
