Revert "added -verafxmul compiler option to use vera fx multiplication routine on cx16"
...
This reverts commit 690782bf
.
It was too risky, using vera (especially fx) transparently in multiple places especially perhaps in IRQ handlers will create havoc unless much intricate care is taken to save/restore the vera state. Better to do vera fx explicitly where the programmer has full control.
