linkersets: Revert to zero-length arrays

Browse Source 
This partially reverts commit 7ec08391fe.

Since the RTEMS_DEFINE_GLOBAL_SYMBOL_IN_SECTION() cannot control the
alignment of the symbol it cannot be used to define the begin of a
linker set.  File scope basic __asm__ statements cannot have operands,
so there is no way to specify the desired alignment.
