nptl:arm: add a wrapper for .cfi_sections pseudo-ops
ARM disables by default the support for ASM CFI directives.
Anyway using an old version of binutils that does not support some new
pseudo-op, the build fails as below:
AS libpthread/nptl/sysdeps/unix/sysv/linux/close.oS
libpthread/nptl/sysdeps/unix/sysv/linux/close.S: Assembler messages:
libpthread/nptl/sysdeps/unix/sysv/linux/close.S:9: Error: unknown pseudo-op: `.cfi_sections'
The problem is that the .cfi_sections pseudo should be wrapped by a macro
that expands to nothing when the CFI is off.
