Comment # 14 on bug 1177260 from Egbert Eich

I've converted netlib-lapack and openblas so that their respective blas &
lapack libraries are held and switched together. This was not without
challenges - as can be seen from
https://github.com/e4t/brp-check-suse/commit/9769cc60206f2ba54466f471705cbfae15fa57fe
I don't particularly like update-alternatives, they are inflexible because
system wide - your suggestion to use LD_LIBRARY_PATH for a user to override the
system wide settings is exactly what environment modules are doing.

Flexiblas seems to be a good abstraction, it should work well with the changes
I've made, however, I won't be looking at it this time - I had my share of
packaging for this time - life would be easier if 'osc build' would allow to
pick up from and rerun later stages of the build process without having to go
thru the 'build' stage every time :(
