Add and use sysdeps/i386/link-defines.sym
Define macros for fields in La_i86_regs and La_i86_retval and use them in dl-trampoline.S, instead of hardcoded values. * sysdeps/i386/Makefile (gen-as-const-headers)[elf]: Add link-defines.sym. * sysdeps/i386/dl-trampoline.S: Include <link-defines.h>. (_dl_runtime_profile): Use LONG_DOUBLE_SIZE, LRV_SIZE, LRV_EAX_OFFSET, LRV_EDX_OFFSET, LRV_ST0_OFFSET, LRV_ST1_OFFSET and LR_SIZE. * sysdeps/i386/link-defines.sym: New file.
