The config option itself is omitted on purpose, headers need to be reviewed and generic *_chk() functions need to be first provided. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net>

* nptl:arm: add a wrapper for .cfi_sections pseudo-opsCarmelo Amoroso2011-02-251-0/+5
| | | | | | | | | | | | | | | | 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.
