arch: add softfp support

Some architectures support a mixed hard/soft floating point, where
the compiler emits hardware floating point instructions, but passes
the operands in core (aka integer) registers.

For example, ARM supports this mode (to come in the next changeset).

Add support for softfp cross compilers to the GCC and GLIBC
configuration. Needed for Ubuntu and other distros that are softfp.

    21 3- Configuring a toolchain

    22     - Interesting config options

    23     - Re-building an existing toolchain

    24     - Using as a backend for a build-system

    25 

    26 4- Building the toolchain

    27     - Stopping and restarting a build

    28     - Testing all toolchains at once

    29     - Overriding the number of // jobs

    30     - Note on // jobs

    31     - Tools wrapper

    32 

    33 5- Using the toolchain

    34     - The 'populate' script

    35 

    36 6- Toolchain types

    37     - Seemingly-native toolchains

    50 9 - How is a toolchain constructed?

    51     - I want a cross-compiler! What is this toolchain you're speaking about?

    52     - So, what are those components in a toolchain?

    53     - And now, how do all these components chained together?

    54     - So the list is complete. But why does crosstool-NG have more steps?

    57 

    58 B- Known issues

    59     - gcc is not found, although I *do* have gcc installed

    60     - The extract and/or path steps fail under Cygwin

    61     - uClibc fails to build under Cygwin

    62     - On 64-bit build systems, the glibc (possibly eglibc too) build

    63       fails for 64-bit targets, because it can not find libgcc

    64     - libtool.m4: error: problem compiling FC test program

    65     - unable to detect the exception model

    66     - configure: error: forced unwind support is required

    67     - glibc start files and headers fail with: [/usr/include/limits.h] Error 1
