While doing this use standard names for start/end
so we could use definitions straight from asm-generic
for all the typical symbols.
This also allowed us to drop the use of PROVIDE in the linker
script so sprc is less non-standard on this area.

Build tested with defconfig for sparc and sparc64.
I do not expect any problems with this patch.
