[PATCH] linux: Add soft-fp folder for arm with --without-fp

[Adhemerval Zanella]

Currently --without-fp does not add the soft-fp folder before
the generic dbl-64 and flt-32 on arm-linux-gnueabi.  This patch adds
the required Implies file (similar as powerpc, mips32, and
m68k-coldfire have done).

It fixes the math failures:

FAIL: math/test-float-double-add
FAIL: math/test-float-double-div
FAIL: math/test-float-double-mul
FAIL: math/test-float-double-sub

FAIL: math/test-ifloat32x-fma
FAIL: math/test-ifloat64-fma
FAIL: math/test-ildouble-fma
FAIL: math/test-ldouble-fma

Since the generic fadd, fdiv, fmul, fsub, and fma routines for float
and double requires fenv support to be correctly rounded.

Checked with a arm-linux-gnueabi configured with --without-fp.
