The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.
Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure. Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.
Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.
find their parent GCC package libraries first in RPATH at install time
but will correctly resolve to their own copies at runtime thanks to the
additional paths encoded at build time. Fixes CHECK_WRKREF builds.
This packages provides GCC support libraries from gcc49 in a specific
location and allows packages to depend on just the libraries rather than
having to pull in the full GCC package. It is heavily based on
lang/gcc47-libs.
