build: Allow simple fixed library names.

This is the current state of OpenBLAS library naming for the pkgsrc
packages (NetBSD and cross-platform).

The idea is to be able to

1) be able to have a stable library name to expect from the build
2) install multiple variants next to each other (single-threaded, parallel)

For this, the new switch FIXED_LIBNAME is introduced. The build uses

make FIXED_LIBNAME=1 LIBNAMESUFFIX=openmp

In the case of 64 bit indices, it uses

make FIXED_LIBNAME=1 LIBNAMESUFFIX=openmp  INTERFACE64=1 LIBSOBASENAME=openblas64

This results in what I assumed to be the intention of the name variables to
begin with, namely primary predictable library names like

libopenblas_openmp.so
libopenblas64_openmp.so

(As pkgsrc keeps a list of expected file names resulting from a build on the user
machine, too funky names with CPU model in there and symlinks are too funky.)

I see that the naming scheme of the 64 bit indices lib is still under discussion, along
with symbol suffix. So far, we use the names without renamed symbols. They are
all installable at the same time and user software can choose which one to use, also
using the pkg-config file (which could be handled more elegantly). Without an established
convention, I didn't think like we should make the call. Depends on what downstream
packages use at some point.

I don't say that I do not cause more mess than necessary, or that I fully understand
the already pesent mess. Just throwing this suggestion out there. Maybe my the
FIXED_LIBNAME switch or something along that can be included. Or we work out
something better that fulfills the demands of a pkgsrc installation.

See the github mirror of pgksrc for the patches in use.

https://github.com/NetBSD/pkgsrc/tree/trunk/math/openblas
https://github.com/NetBSD/pkgsrc/tree/trunk/math/openblas64
https://github.com/NetBSD/pkgsrc/tree/trunk/math/openblas_openmp
https://github.com/NetBSD/pkgsrc/tree/trunk/math/openblas64_openmp
https://github.com/NetBSD/pkgsrc/tree/trunk/math/openblas_pthread
https://github.com/NetBSD/pkgsrc/tree/trunk/math/openblas64_pthread

Also, I hope I didn't break any other configuration.

And, lastly, one idea: If we settle on OpenMP always and the ILP64 symbols with suffix, we
could just get away with building _one_ libopenmp.so (with libtool versioning, perhaps,
libopenblas.so.0.4.33 and symlinks …). That would also be great and lots of
Makefile machinery could go. Until then, please consider my hack on top;-)
