It includes the correct buildlink3.mk file from either Linux-PAM
(security/PAM) or OpenPAM (security/openpam) and eventually will
support solaris-pam. pam.buildlink3.mk will:
* set PAMBASE to the base directory of the PAM files;
* set PAM_TYPE to the PAM implementation used.
There are two variables that can be used to tweak the selection of
the PAM implementation:
PAM_DEFAULT is a user-settable variable whose value is the default
PAM implementation to use.
PAM_ACCEPTED is a package-settable list of PAM implementations
that may be used by the package.
Modify most packages that include PAM/buildlink3.mk to include
pam.buildlink3.mk instead.
package from "pam" to "linux-pam".
* Rewrite PAM/builtin.mk to check that we have Linux-PAM, and re-classify
MacOS X's PAM as Linux-PAM because it _is_, according to to Apple.
Also don't use BUILDLINK_TRANSFORM.* to rewrite header file paths
-- just use a symlink so that <security/*.h> can be used to find
<pam/*.h>.
into the bsd.options.mk framework. Instead of appending to
${PKG_OPTIONS_VAR}, it appends to PKG_DEFAULT_OPTIONS. This causes
the default options to be the union of PKG_DEFAULT_OPTIONS and any
old USE_* and FOO_USE_* settings.
This fixes PR pkg/26590.
