Most probably yes, but the previous part of the code (which joins the 
lines defining a dynamic linker) will also need to be modified to take 
GNU_USER_DYNAMIC_LINKER into account, as the code also substitutes some 
entries in the linux.h files, which are usually multiline (most of the 
time, a CHOOSE_DYNAMIC_LINKER macro)...

Sorry, I'm way too weak of a schemer to do that, even though it's 
probably incredibly simple...
