Yes:

  http://autobuild.buildroot.net/?reason=<package-version>

so:

  http://autobuild.buildroot.net/?reason=host-libsemanage-2.7

So it is the first time that this happens.

Autotools typically has a separate sysconfdir option, which is not
subject to prefix:

                --prefix=/usr \
                --exec-prefix=/usr \
                --sysconfdir=/etc \

What is the problem with using the standard semantic?
DESTDIR=$(HOST_DIR) PREFIX=$(HOST_DIR) is not correct because files
would be installed in $(HOST_DIR)/$(HOST_DIR). Just DESTDIR=$(HOST_DIR)
PREFIX=/usr is not correct, because that means the program/library
expects to be executed from /usr.

Right. Though perhaps we should wait for upstream's feedback. I'm a bit
unsure of what will be upstream's reaction to those patches, so perhaps
wait for feedback before fixing all the remaining packages ?

Best regards,
