With Al Viro <viro@parcelfarce.linux.theplanet.co.uk> To make sure switcheroo() can execute when we remap all the executable image, we used a trick to make it use a local copy of errno... this trick does not work with NPTL glibc, only with LinuxThreads, so use another (simpler) one to make it work anyway. Hopefully, a lot improved thanks to merging with the version of Al Viro (which had his part of problems, though, i.e. removing a fix to another bug and not fixing the problem on i386).
