In commit 22acd3654a ("Add IUSE=blas.") I
tried to add support for linking against a BLAS implementation as
suggested in liblinear's documentation.
As so far liblinear does not support any helpers for linking against it
as well as a BLAS library in an automated way, enabling USE=blas can
result in linking failures in packages that are unaware of the BLAS
linkage. Until a pkg-config file or other reliable source for library
linkage is provided with liblinear, usage of an external BLAS library
cannot be supported.
