Configure blis to be compatible with f2cblaslapack in complex arithmetic
Apparently compilers differ in how they handle complex number return types from fortran:
some return on the stack (GNU) others insert an additional argument (Intel). f2cblaslapack
is fortran that has been translated into C using the latter style. But this means that
if f2cblaslapack is going to call blis, blis has to make sure its blas compatibility layer
matches. If we don't tell blis which format to use, it guesses using the fortran compiler
that it knows about, and it might guess wrong. So we add a flag to blis
configuration to control the complex return type, and we have
f2cblaslapack set the default value of that flag when
--download-f2cblaslapack is used.
Without this change, 'mat_tests-ex120_*' tests are broken if blis returns complex numbers
on the stack. We haven't detected this yet because we do not have a blis/f2cblaslapack/complex
arch in CI.
