Remove the arm26 port

The arm26 port has been in a state where it was far from even compiling
for quite some time.

Ian Molton agreed with the removal.

-/* This is the kernel's entry point into the floating point emulator.
-It is called from the kernel with code similar to this:
-
-	mov	fp, #0
-	teqp	pc, #PSR_I_BIT | SVC_MODE
-	ldr	r4, .LC2
-	ldr	pc, [r4]		@ Call FP module USR entry point
-
-The kernel expects the emulator to return via one of two possible
-points of return it passes to the emulator.  The emulator, if
-successful in its emulation, jumps to ret_from_exception and the
-kernel takes care of returning control from the trap to the user code.
-If the emulator is unable to emulate the instruction, it returns to
-fpundefinstr and the kernel halts the user program with a core dump.
-
-This routine does four things:
-
-1) It saves SP into a variable called userRegisters.  The kernel has
-created a struct pt_regs on the stack and saved the user registers
-into it.  See /usr/include/asm/proc/ptrace.h for details.  The
-emulator code uses userRegisters as the base of an array of words from
-which the contents of the registers can be extracted.
-
-2) It locates the FP emulator work area within the TSS structure and
-points `fpa11' to it.
-
-3) It calls EmulateAll to emulate a floating point instruction.
-EmulateAll returns 1 if the emulation was successful, or 0 if not.
-
-4) If an instruction has been emulated successfully, it looks ahead at
-the next instruction.  If it is a floating point instruction, it
-executes the instruction, without returning to user space.  In this
-way it repeatedly looks ahead and executes floating point instructions
-until it encounters a non floating point instruction, at which time it
-returns via _fpreturn.
-
-This is done to reduce the effect of the trap overhead on each
-floating point instructions.  GCC attempts to group floating point
-instructions to allow the emulator to spread the cost of the trap over
-several floating point instructions.  */
