BUG 11929: Build 'bind'-binaries dynamically and install needed libraries (V2)

Hi,

To save space linking the 'bind 9.11.5'-binaries was changed from statically to dynamically.

Changes to V2:
Removed unnecessary '*.so'-links.

Complete file sizes shrinked from ~4800K to ~1700K. Needs testing and confirmation!

I'm running this version right now under Core 124 - no seen problems so far.

Best,
Matthias
