"fortran" -> "fortran77" except where it is clear that it \ 
isn't F77.
"fortran" is alias of "fortran77" for now, but it will \ 
change later.

Log message:
Detect if the fortran compiler/libs have etime as an intrinsic or not instead
of hard coding it.  This package builds with both f2c and gfortran now.

Log message:
Added LICENSE information.

patch-ad: Don't remove the $(NOOPT) for slamch.f and dlamch.f
Was probably done unintentionally and caused infinite loops on some platforms.
Patch from Aleksey Cheusov in PR pkg/38371.

Log message:
Simply and speed up buildlink3.mk files and processing.
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.

Log message:
Use MASTER_SITE_NETLIB for Netlib and its mirrors.
Discussed with Tobias Nygren.

Log message:
Tell libtool that its linking fortran so the correct libraries get linked
in.
