Subject: [PATCH] ANDROID: Use -fomit-frame-pointer for
 x86_ptrace_syscall_x86_64

do_full_int80() in ptrace_syscall.c uses bp register in inline
assembly. It doesn't work when frame pointer is not omitted.

After clang update, by default frame pointer isn't omitted
on x86_64. So explictly use -fomit-frame-pointer.
