Details:

The attached changeset (blaswrap.diff) adds checks to configure.ac to retry
incompatible fortran compiler in two ways:

1) Try with the "-ff2c" option, i.e. to use the F2C calling convention. This
is required with e.g. 32-bit OSX, when using the Apple provided BLAS and
LAPACK libraries, but may also work with other platforms

2) On OSX, try with an OSX specific libcruft/misc/blaswrap.c, which converts
the F2C calls in libBLAS.dylib and libLAPACK.dylib to the native gfortran
calling convention. This is required with 64-bit OSX, if using the Apple
provided BLAS and LAPACK libraries.
