SV platform dependency builds

# This Makefile.am specifies a set of codelets, efficient transforms

# of small sizes, that are used as building blocks (kernels) by FFTW

# to build up large transforms, as well as the options for generating

# and compiling them.

# You can customize FFTW for special needs, e.g. to handle certain

# sizes more efficiently, by adding new codelets to the lists of those

# included by default.  If you change the list of codelets, any new

# ones you added will be automatically generated when you run the

# bootstrap script (see "Generating your own code" in the FFTW

# manual).
