[Buildroot] [pull request] Pull request for branch libatomic-arch

[Thomas Petazzoni]

Hello,

Here is a fix about libatomic_ops. However, it is worth noting that
according to http://www.hpl.hp.com/research/linux/atomic_ops/, the
official website of libatomic_ops, this library is no longer
maintained. It is currently used by libdrm and pulseaudio in
Buildroot. Does anyone knows what are the up-to-date andmaintained
alternatives?

Best regards,

Thomas

[Buildroot] [PATCH 1/1] libatomic_ops: make it available only on supported architectures

[Thomas Petazzoni]

libatomic_ops build fails on architectures such as MIPS or SuperH that
are not supported. So we make it possible to select the libatomic_ops
package only for the architectures that are known to be supported.

It seems like you forgot BR2_armeb - I've added that and committed,
thanks.
