This is a Kconfig cockup. If you have the libsas with ATA support, it
needs libata to function. The problem is that if you compile in libsas,
you can't build libata as a module (however, vice versa you can).
About the only way I can think to code this in current Kconfig is the
attached rather ugly code.

Builds in ATA support into libsas. Will necessitate
the loading of libata along with libsas.
