Giuseppe CAVALLARO 94ab115fd3 sh: fix vsyscall compilation due to .eh_frame issue
This patch fixes the following error obtained when
compile the Kernel with the VSYSCALL support enabled:

  SYSCALL arch/sh/kernel/vsyscall/vsyscall-trapa.so
  sh4-linux/bin/ld: error in arch/sh/kernel/vsyscall/vsyscall-trapa.o(.eh_frame);
  no .eh_frame_hdr table will be created.
  AS      arch/sh/kernel/vsyscall/vsyscall-syscall.o

Disassembling the vsyscall-trapa.o code, with this fix applied,
we get the __kernel_vsyscall symbol defined; otherwise it was
missing.

Disassembly of section .text:
