nvptx: Don't use global constructor for SSP setup
Given that nvptx newlib currently restricts itself to ELIX level 1, this
is not already a problem. However, in the following we'd like to lift
that restriction, and then run into:
[...]/newlib/libc/ssp/stack_protector.c: In function ‘__stack_chk_init’:
[...]/newlib/libc/ssp/stack_protector.c:31:1: sorry, unimplemented: global constructors not supported on this target
31 | }
| ^
GCC patch "nvptx: Support global constructors/destructors via 'collect2'"
has been posted, but not yet accepted. Until that is resolved, use the
same manual SSP setup as for GCN.
