@TYPE1INST@ should be replaced with ${TOOLS_PATH.type1inst}.
Before this change, the sed(1) script being generated was not
replaced @TYPE1INST@ at all, and instead generating a no-op
substitution pattern for TTMKFDIR.
LDCONFIG_ADD_CMD and LDCONFIG_REMOVE_CMD are set by emulator/*.mk
in order to update the library search paths in the emulated system
directories. Substitute for those values, but default them to the
empty string so that the default action taken by the "shlibs" task
can be used.
Add missing feature from "pkginstall" framework where the config
directory ${PKG_SYSCONFDIR} was automatically created if one of
the following conditions were true:
* PKG_SYSCONFSUBDIR was defined and non-empty.
* Any configuration files were copied into ${PKG_SYSCONFDIR}.
A full dependency on the "pkgtasks" package will be added if a
non-empty data file is generated by the framework.
This framework is not yet hooked into bsd.pkg.mk, pending some
other changes.
