Add jmp_buf-macros.h

Verify that sizes, alignments and field offsets of jmp_buf as well as sigjmp_buf are unchanged regardless how struct __jmp_buf_tag is defined. Since jmp_buf is target specific, jmp_buf-macros.h is added for each Linux target. A new target must provides its own jmp_buf-macros.h. TODO: Hurd needs to provide a jmp_buf-macros.h. Tested with build-many-glibcs.py. * include/setjmp.h [!_ISOMAC]: Include <stddef.h> and <jmp_buf-macros.h>. [!_ISOMAC] (STR_HELPER): New. [!_ISOMAC] (STR): Likewise. [!_ISOMAC] (TEST_SIZE): Likewise. [!_ISOMAC] (TEST_ALIGN): Likewise. [!_ISOMAC] (TEST_OFFSET): Likewise.
