No.  It is a source code modification, which is the problem.  You _might_ be
able to use a debugger and find the spinlocks, but inserting a pause instruction
might not be possible as it will mean "stretching" the code which would break
things without some cute tricks, such as a jump out to the lock and a jump
back...

I wouldn't want to think about it not having any idea where the locks really
are.  :)
