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.
