// of figuring section flags. If the user wrote section(".eh_frame"),
// we should just pass that to MC which will defer to the assembly
// or use its default if producing an object file.
// N.B.: The defaults used in here are no the same ones used in MC.
// We follow gcc, MC follows gas. For example, given ".section .eh_frame",
// both gas and MC will produce a section with no flags. Given
// section(".eh_frame") gcc will produce
// .section .eh_frame,"a",@progbits
