[Buildroot] [PATCH v2 0/4] Optionally build some skarnet.org packages as multicall binaries

[Buildroot] [PATCH v2 0/4] Optionally build some skarnet.org packages as multicall binaries

[J. Neuschäfer via buildroot]

In recent years, execline, s6-portable-utils, and s6-linux-utils gained
the ability to be built as a multicall binary, just like busybox.
This patchset exposes the multicall option in Buildroot.

Given that 2024.08-rc1 has just been tagged, and this is not a bugfix
series, it should probably be applied to the next branch instead of
master.

[Buildroot] [PATCH v2 1/4] package/execline: Add option to build multicall binary

[J. Neuschäfer via buildroot]

Since version 2.9.2.0, with another bugfix in 2.9.4.0, execline can
be built as a multicall binary, similar to busybox. According to
the author[1], this results in space savings of 66-87% on Linux.
