It uses fork(), so it needs to depend on BR2_USE_MMU. It also uses
TEMP_FAILURE_RETRY which isn't available on musl, so it should only be
available for glibc/uclibc - Notice that 0.4.0 was recently released
which according to the changelog fixes builds against musl.

Committed with these fixes, thanks.

I wonder what kernel namespacing options are required and/or
recommended? For required options we should add logic in linux/linux.mk
to enable them, and for optional/recommended options it would be good to
mention them in the help text.
