[Buildroot] NPTL compile error without MMU (ARM)

[Sangjung]

Dear developers.

Hi. I found out that nptl make a compile error when MMU (i.e. 'Toolchain 
- Enable MMU support')  is disabled.

Detailed error message is as below.

This problem is already reported by Axel Lin.
(Link: http://lists.uclibc.org/pipermail/uclibc-cvs/2013-May/031094.html)

However, it looks like that this issue is not solved for a long time.
If someone let me know the alternative solution, I'd be really happy.

Thank you in advances.

BRs,
