[Buildroot] [git commit] lz4: install programs as well as libraries

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=6f1c11f79a64387c1f1749550804f8aae0cfa7a7
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Prior to commit 8ad38a4fc2007df4bee9a941aed46c8771b6a84c
("package/lz4: bump version to r131"), the lz4 package was installing
both libraries and programs, but this commit changed the behavior to
only install libraries.

The contributor might have been confused by the fact that the build
command was "$(MAKE) ... -C $(@D) liblz4", suggesting that only the
library was built. But since the install command was "$(MAKE) ... -C
$(@D) install", the programs were effectively built as part of the
install step, and installed as well.

Since it makes sense for lz4 to also installs its programs, this
commit adjusts the package accordingly.

It is worth mentioning that using the "all" target during the build
step is important. Indeed, otherwise the programs/Makefile has a
"default" target that doesn't build everything (especially the lz4c
program) and it end up being built as part of the install step, due to
how the makefile dependencies are handled in the lz4 project. To make
sure that everything gets built during the build step, we explicitly
use the "all" target.

Fixes bug #9996
