[patches] MIPS local_lim.h

["Joseph S. Myers" <joseph@xxxxxxxxxxxxxxxx>]

I've applied this patch to give MIPS its own version of bits/local_lim.h.  
This is necessary because the default Linux NPTL version has too small a 
value of PTHREAD_STACK_MIN for 64k pages and parts of glibc try to create 
threads with that stack size.  (Power has its own version of the header 
with the same enlarged PTHREAD_STACK_MIN for the same reason.)
