[PATCH] Fix building microblaze targets with trunk

[Jeff Law]

The microblaze port as a "*p++" statement which computes a result that 
is never used (the memory result).  This removes the spurious memory 
dereference and the unused value warning.

Tested by building the microblaze targets in config-all.mk.
Installed on the trunk.
