[PATCH v1 1/7] rtembsd: Fix alignment of allocations for 64bit

[Kinsey Moore]

Thus far, GCC has been just fine other than violating some behavioral expectations that
were never guaranteed (the linker sets patches). Newlib has some ILP32 issues that need
to be addressed. I've gotten a patch into the upstream ARM optimized routines that will
eventually make it into Newlib and fix those issues. There's possibly another issue with
the "dc zva" instruction that may also be solved by enabling the MMU.

Thanks for the explanation. I hope this is not common and tools like gcc etc are
more supportive of ILP32.
