setjmp: Replace jmp_buf-macros.h with jmp_buf-macros.sym 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. 2021-11-19 14:06:00 +00:00			`#include <setjmp.h>`
