[uClibc] ldd doesnt pass along LD_LIBRARY_PATH

[Mike Frysinger]

when i was trying to track down some linking troubles i was having, i noticed 
that running `env LD_LIBRARY_PATH=/somewhere ldd /somefile` wasnt producing 
the correct results ...

when the environment is created to run the program you are `ldd`-ing, the 
LD_LIBRARY_PATH isnt passed along thus creating this discrepancy in display

find attached a small patch to fix this ... i'm sure someone can figure out a 
much cleaner one, but this seems to work and at least serves as a proof of 
fix :)
