Hi Andrew,
Is that from a clean clone of the repository? I wonder if a change to a
generated file isn't being picked up somewhere by "make distclean". My
standard build script is this:
make distclean
'./configure' '--target-list=x86_64-softmmu sparc64-softmmu
sparc-softmmu ppc-softmmu arm-softmmu' '--disable-pie'
System is standard Debian wheezy on amd64.
ATB,
Mark.
