No.  This is wrong, and a NOP change.  Please back this out.

The reason why is because libtermcap.so is a symlink to libncurses.  And 
libncurses has a DT_SONAME of "libncurses.so.5".  This means 

peter at daintree[5:51pm]~-25> objdump --all-headers /usr/lib/libtermcap.so 
| grep SONAME
  SONAME      libncurses.so.5

Any dependencies will be silently "fixed" by ld, so no matter what, you 
end up with a DT_NEEDED of libncurses.so.5.  Except that by using the 
wrong name, you obfuscate things.

peter at daintree[5:53pm]~-30> cc -o x x.c -ltermcap
peter at daintree[5:53pm]~-31> objdump --all-headers x | grep NEED
  NEEDED      libncurses.so.5
  NEEDED      libc.so.5
peter at daintree[5:53pm]~-32> cc -shared -o x.so x.c -ltermcap
peter at daintree[5:53pm]~-33> objdump --all-headers x.so | grep NEED
  NEEDED      libncurses.so.5
