Subject: build: support 'dist' and 'syntax-check' targets without libselinux
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=01993d76bc6c14004200c5a4c00bb9a1881514ea;p=thirdparty%2Fcoreutils.git

build: support 'dist' and 'syntax-check' targets without libselinux

Following on from commit v9.8-60-g8ba47d09a ...
Without libselinux installed, runcon and chcon stub binaries
will not be built by default.  We separate these utilities out
to a separate "not built unless appropriate" class, so that
we can add these to EXTRA_MANS so that the 'check-x-vs-1'
target doesn't fail, and the 'dist' target includes
these man pages.

* build-aux/gen-lists-of-programs.sh: Separate out
build_if_appropriate_progs, and propagate that through
to no_install_progs_default which populates EXTRA_MANS.
* src/local.mk: Separate out build_if_appropriate__progs
for clarity and consistency.
