Linking lapack with the gold linker fails with this error:
fatal error: --sysroot=: must take a non-empty argument
DragonFly has been using the gold linker by default for a while now.
Since I don't have time to track down this linking problem, I'm going
to restore the build on DragonFly by setting an environment variable
that forces DF to use the classic GNU linker instead.
This was already fixed on math/blas which uses the lapack common
makefile, so just relocate the fix to lapack.

LAPACK 3.6.1: What’s new
[Mark Gates, UTK] blocked back-transformation for the non-symmetric eigenvalue problem
It blocks NB gemv calls into one gemm call inside trevc. To do
that, it needs a new routine, trevc3, because unfortunately the
lwork was not passed into trevc. Attached is the performance speedup
for dgeev. It gives a nice 1.5x speedup for N=20000, and that
appears to still be increasing with N. This is not the improvements
that Greg Henry recently provided for doing the triangular solves
as BLAS-3 instead of BLAS-1. That will take a while to process,
but we expect another, even larger increase in performance when
those changes are applied. This also does not include doing multiple
(BLAS-1) triangular solves in parallel, which is available in MAGMA,
since that requires OpenMP or pthreads.

* added Symmetric/Hermitian LDLT factorization routines with rook pivoting algorithm
* 2-by-1 CSD to be used for tall and skinny matrix with orthonormal columns (in LAPCK 3.4.0, we already integrated CSD of a full square orthogonal matrix)
* New stopping criteria for balancing.

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.

RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).

framework. The list of changes include:
* Modify compiler.mk so that "c" is always prepended to USE_LANGUAGES,
so we no longer need to say it in package Makefiles. Packages
should now append to USE_LANGUAGES instead of setting it.
* Create mk/compiler/f2c.mk which implements another pseudo-compiler
"f2c" that may be used with any C compiler backend, e.g.
PKGSRC_COMPILER= f2c ccache gcc
* Teach the various "real" compiler files, e.g., sunpro.mk, mipspro.mk,
etc., to use f2c if the native Fortran compiler isn't present.
Packages that use Fortran should now simply include the line:
USE_LANGUAGES+= fortran
in the package Makefile.

Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and

All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".
