 Please don't.  The emulation is an overkill here and the overhead is
painful for ISA I systems, which are usually not the fastest ones.  This
has already been discussed here.

 If you want to go for speed and use ll/sc on an ISA II+ system, then
compile glibc for ISA II or better.  It will never call sysmips() then.
