I have reverted the linux-specific changes for printing out registers
and the state of the FPU.

We would very much like to restore this lost functionality by unifying
FP support for the various i386 implementations.  I know that a number
of you were active in discussions regarding FP support unification
earlier this summer.  If you have patches, send them our way!  :)

Those of you watching the number of test suite failures on Linux will
notice that there is now one more failure than before (info float).
