[Qemu-devel] [Bug 1363641] Re: Build of v2.1.0 fails on armv7l due to undeclared __NR_select

[Karl-Philipp Richter]

** Description changed:

  After `make clean` and `git clean -x -f -d` `git checkout v2.1.0 &&
  configure --prefix=/home/user/prefix-qemu-2.1.0 && make` fails due to
  missing declarations
