[PATCH] uml: fix linkage of tt mode against NPTL
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).
