gcc44: Instruct linkers to create GNU hash tables

The real-time linker has just been taught how to use GNU hash tables
to speed up symbol lookup.  However, the linkers only generate SysV
hashes by default, so the specs file is being altered to generate
both types of hashes for every shared library and dynamic executable
for a while.  Maybe after a release or two we can consider only
generating the superior GNU hash, which will break forward compatibility
with older releases.
