It would be nice if the gcc ebuilds could automatically install compiler profiles for, e.g., forced --as-needed / --no-add-needed 

Obviously this is nothing for Joe Average User, so it should be controlled by a flag and off by default. It certainly beats creating the profiles by hand after every gcc upgrade, though...

the only thing a profile is is a custom spec file.  i dont want to explode the profile list for arbitrary flags, so simply create your own:
 - `gcc -dumpspecs > f`
 - add --as-needed to link_command
 - export GCC_SPECS to $PWD/f

if you want to automate things, then use the per-package bashrc
