The reference (netlib) LAPACK implementation exports `lsame_` unconditionally. When trying to use libflame as a drop-in replacement for the reference implementation on Windows, programs fail to start with an error that the symbol `lsame_` is undefined. IIUC, that is because the symbol resolution is done on link time for Windows (instead of at runtime on most other platforms). The proposed change makes sure that `lsame_` is exported from libflame even if configured with `--disable-lapack2flame --disable-builtin-blas` (the default). IIUC, an alternative would be to export this symbol defined in `src/flablas/f2c/lsame.c`. But the proposed change is a bit closer to the reference implementation.
