Revert "[PARISC] import necessary bits of libgcc.a"

This reverts commit efb80e7e, it turned
out to cause sporadic problems with the timer interrupt on 32-bit kernels.
Needs more investigation.

-
-   Single precision divide for signed binary integers.
-
-   The quotient is truncated towards zero.
-   The sign of the quotient is the XOR of the signs of the dividend and
-   divisor.
-   Divide by zero is trapped.
-   Divide of -2**31 by -1 is trapped for $$divoI but not for $$divI.
-
-   INPUT REGISTERS:
-   .	arg0 ==	dividend
-   .	arg1 ==	divisor
-   .	mrp  == return pc
-   .	sr0  == return space when called externally
-
-   OUTPUT REGISTERS:
-   .	arg0 =	undefined
-   .	arg1 =	undefined
-   .	ret1 =	quotient
-
-   OTHER REGISTERS AFFECTED:
-   .	r1   =	undefined
-
-   SIDE EFFECTS:
-   .	Causes a trap under the following conditions:
-   .		divisor is zero  (traps with ADDIT,=  0,25,0)
-   .		dividend==-2**31  and divisor==-1 and routine is $$divoI
-   .				 (traps with ADDO  26,25,0)
-   .	Changes memory at the following places:
-   .		NONE
-
-   PERMISSIBLE CONTEXT:
-   .	Unwindable.
-   .	Suitable for internal or external millicode.
-   .	Assumes the special millicode register conventions.
-
-   DISCUSSION:
-   .	Branchs to other millicode routines using BE
-   .		$$div_# for # being 2,3,4,5,6,7,8,9,10,12,14,15
-   .
-   .	For selected divisors, calls a divide by constant routine written by
-   .	Karl Pettis.  Eligible divisors are 1..15 excluding 11 and 13.
-   .
-   .	The only overflow case is -2**31 divided by -1.
-   .	Both routines return -2**31 but only $$divoI traps.  */

-   .
-   .	Single precision divide for unsigned integers.
-   .
-   .	Quotient is truncated towards zero.
-   .	Traps on divide by zero.
-
-   INPUT REGISTERS:
-   .	arg0 ==	dividend
-   .	arg1 ==	divisor
-   .	mrp  == return pc
-   .	sr0  == return space when called externally

-   OTHER REGISTERS AFFECTED:
-   .	r1   =	undefined
-
-   SIDE EFFECTS:
-   .	Causes a trap under the following conditions:
-   .		divisor is zero
-   .	Changes memory at the following places:
-   .		NONE
-
-   PERMISSIBLE CONTEXT:
-   .	Unwindable.
-   .	Does not create a stack frame.
-   .	Suitable for internal or external millicode.
-   .	Assumes the special millicode register conventions.
-
-   DISCUSSION:
-   .	Branchs to other millicode routines using BE:
-   .		$$divU_# for 3,5,6,7,9,10,12,14,15
-   .
-   .	For selected small divisors calls the special divide by constant

-   .	$$remI returns the remainder of the division of two signed 32-bit
-   .	integers.  The sign of the remainder is the same as the sign of
-   .	the dividend.

-
-   INPUT REGISTERS:
-   .	arg0 == dividend

-   .	mrp  == return pc

-   .	arg1 = destroyed
-   .	ret1 = remainder
-
-   OTHER REGISTERS AFFECTED:
-   .	r1   = undefined
-
-   SIDE EFFECTS:
-   .	Causes a trap under the following conditions:  DIVIDE BY ZERO
-   .	Changes memory at the following places:  NONE
-
-   PERMISSIBLE CONTEXT:
-   .	Unwindable
-   .	Does not create a stack frame
-   .	Is usable for internal or external microcode
-
-   DISCUSSION:
