-D_GNU_SOURCE.
* plugin/plugin-hsa.c: Include config.h, inttypes.h and stdbool.h.
Handle various cases of secure_getenv presence, add an implementation
when we can test effective UID and GID.

(hsa_fatal): Likewise.
(DLSYM_FN): New macro.
(init_hsa_runtime_functions): New function.
(suitable_hsa_agent_p): Call hsa run-time functions via hsa_fns
structure. Depending on environment, also allow CPU devices.
(init_hsa_context): Call hsa run-time functions via hsa_fns structure.
