build: consolidate some common parts of linker scripts

Browse source 
There are a number of data sections that are repeated across
all the linker scripts for various architecture. In practice these
don't always get updated and we have had problems with bit-rot.
Consolidate these to make maintenance easier.

x86 linker scripts now follow the same naming convention and we
get rid of a linker-epilog.h that wasn't necessary and whose purpose
has been lost to the mists of time. If applications want to define their
own sections they should be allowed to. Linker scripts for x86 do not
end with .h any more, they are not C header files even though we use
C's preprocessor.
