The "_" symbol prefix added by the blackfin toolchain causes "undefined symbol" build failures when the compiler is trying to link a binary with libblas and/or liblapack. This patch also disables clapack reverse dependencies: armadillo.

To optimize BLAS library for the hardware, an 'arith.h' header should
|
|
be provided.
|
|
|
|
If empty, the library will not be optimized by the compiler.
|
|
|
|
In any case an 'arithchk' program is built (but not installed), to be run
|
|
on the target to generate this arith.h header.
