[gentoo-dev] keywording gcc-4.9 branch

[Anthony G. Basile]

Hi everyone,

It looks like there aren't too many bugs against gcc-4.9 (bug #495124).  
There are a couple having to do with lto and one which is hardened 
specific, but its probably a good idea to start keywording on the 
various arches so we can get more bug reports and not trail behind.  So 
I opened bug #536874.

I've followed Ryan's workflow where he has one bug for gcc 4.9 porting 
and another for keywording/stabilization.  I'm not sure why he did it 
this way, but it may be less confusing in the future to have just one 
which track the state of the ebuild from keyword masked, to keyworded to 
stabilization.

@rhill, any advice here :)

Word of warning, asan was still terminally broken on nontrivial code 
last time I tested it.

Its masked by default and only unmasked on amd64, arm, powerpc, sparc 
and x86 with glibc.  Its pretty much broken on other arches, on other 
libc's and on PaX hardened kernels.  See the following bugs:
