[Buildroot] [git commit] uclibc: NPTL thread implementation only available on MMU platforms

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=c218c337c7476a8b0007451117d0510ff10fde55
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

As indicated by the uClibc-ng source code, the NPTL thread
implementation is only available on MMU platforms, so we replicate
this dependency in Buildroot so that the appropriate thread
implementation is chosen by default on ARM noMMU.
