Re: linux-user static build broken

[Paolo Bonzini]

$ORIGIN is a special literal used by ld.so. It's probably fixed by the same patch that was posted for msys.

It's what I'm doing.

There are both "--static-pie" and "--pie" on the new command line, but
keeping only the first doesn't fix the problem.

There is also a strange '-Wl,-rpath,RIGIN/' that would mean "make" is
not using $(ORIGIN) but $ORIGIN...
