Running the java testsuite on arm-elf shows a couple of compile failures
where we emit a '.space 0' directive. Following the ia64 example we avoid
this problem by always allocating at least one byte of space.

* arm/unknown-elf.h (ASM_OUTPUT_ALIGNED_DECL_LOCAL): Always allocate
at least one byte of space.
