        syssrc/sys/arch/alpha/stand/common: prom.c

Log Message:
Experimentation reveals that the implementation of GET_ENV on at least
some systems chokes if the buffer is not 8-byte aligned. GCC only aligns
character arrays to 4-byte boundaries by default, so it's possible to get
unlucky and die in the boot blocks with a "kernel stack not valid halt".

Avoid the problem by using a local, aligned buffer as the argument to GET_ENV,
and copying the result into the caller's buffer.

Should fix PRs port-alpha/17682 and port-alpha/17717.
