Re: [XenPPC] [xenppc-unstable] [XEN][POWERPC] Linker script simplification broke optimized builds.

[Jimi Xenidis <jimix@xxxxxxxxxxxxxx>]

the original script came from binutils and we simply adapted it.
I tried to simplify but I was unable to predict all the gcc created  
sections for various gcc flags (esp -O2), so I just put all that  
stuff back.
I'll try another pass at another time, when I can test all scenarios.
There is a huge degree of risk playing here, you can imagine how hard  
an issues from a dropped section would be hard to detect.  Perhaps ld  
has options to warn when badness occurs.
I got lucky with this one.
