app-eselect/eselect-{blas,lapack}: new design for BLAS/LAPACK switch.
As discussed in the gentoo-dev, it is decided to adopt the runtime
switching of BLAS/CBLAS that has been proved by the experience of
Debian. The Gentoo libgcc-style ld.so.conf runtime switching has
been adopted as well, so as to avoid changing symlinks in /usr
ignoring package manager.
This design solves all the remaining problems regarding BLAS/LAPACK,
thus making alternative-2.eclass (runtime switching of build
options) and proposed USE_EXPAND (PYTHON_TARGET like eclass)
obsolete.
Finally we are at it. Thanks to all for years of ideas, debates and
hard work.
