Both issues were GCC bugs now fixed on mainline. See
https://gcc.gnu.org/PR61231 and http://gcc.gnu.org/PR61336.
The first one was not really related to sys/sdt.h at all. The second was
indeed a bug in GCC on alpha triggered by the usage of the "i"
constrained in the sys/sdt.h asm, now fixed.

Better would be to backport the alpha bug fix for GCC.
