It requires less boilerplate code for newer ports. The _Static_assert checks from internal setjmp are moved to its own internal test since setjmp.h is included early by multiple headers (to generate rtld-sizes.sym). The riscv jmp_buf-macros.h check is also redundant, it is already done by riscv configure.ac. Checked with a build for the affected architectures.
